In this paper, a new method for blind recognition of BCH code from an intercepted sequence of noise affected codewords is proposed. The proposed method recovers the parameters of a BCH code by finding the roots of it's generator polynomial. Firstly, the Galois Field Fourier Transform (GFFT) operation is carried out for each sequence of an estimated length. Then, find the positions of common zero spectral components of all sequences' GFFT. If such positions exist, the corresponding estimated length is the code length and the roots of the underlying generator polynomial are found. Furthermore, the theoretical analysis of the proposed method is given in detail and an optimal threshold is derived to minimize the summation of the false alarm and miss detection probability for distinguishing the root and non-root of the generator polynomial. Simulation results show that the proposed method outperforms the previous ones.

This paper investigates the secrecy outage performance of transmit antenna selection (TAS)/maximal ratio combining (MRC) in multiple input multiple output (MIMO) cognitive radio networks (CRNs) over Rayleigh fading channels. In the considered system, a secondary user (SU-TX) equipped with NA (NA ≥ 1) antennas uses TAS to transmit confidential messages to another secondary user (SU-RX), which is equipped with NB (NB ≥ 1) antennas and adopts MRC scheme to process multiple received signals. Meanwhile, an eavesdropper equipped with NE (NE ≥ 1) antennas also adopts MRC scheme to overhear the transmitted information between SU-TX and SU-RX. SU-TX adopts the underlay strategy to guarantee the quality of service of the primary user without spectrum sensing. In this paper, we derive the closed-form expression for the secrecy outage probability (SOP) and propose a simplified SOP when the maximum transmit power at SU-TX is always sufficiently high. Finally, simulations are conducted to validate the accuracy of our proposed analytical models.

In this paper, we present an efficient transmission scheme for multiple-input multiple-output (MIMO) systems, i.e., low density parity check (LDPC) coded spatial modulation (SM) systems. To exploit the powerful error correction of LDPC code, the key challenge of LDPC coded SM systems is on designing a reliable but low complexity soft-output detector. To tackle this problem, we propose two soft-output detection algorithms based on hard-decision detectors by exploiting the features of M-PSK and M-QAM constellations, namely, PSK-based soft-output detector (PBSOD) and QAM-based soft-output detector (QBSOD). The analytical results show that the number of the searched signal candidates is reduced from NtM to Nt, where Nt is the number of transmit antennas, M is the modulation order. Furthermore, we propose a more general simpler detector, that is, using the absolute value instead of the Frobenius norm to calculate the soft bit metrics. The findings of this paper suggest that the proposed three soft-output detectors for LDPC coded SM systems exhibit lower complexity compared to optimal maximum a posteriori (MAP) log likelihood ratio (LLR) detector and Max-Log detector while imposing only marginal performance degradation. In addition, a comprehensive performance and computational complexity comparison between the proposed detectors and the state-of-the-art detectors is provided to validate the proposed low-complexity detectors. The achieved performance and complexity of the proposed detectors make them suitable candidates for practical coded SM-MIMO systems.

This paper considers the BIA implementation of K-user multiple-input single-output (MISO) interference channel (IC) without CSIT, in which each transmitter is equipped with Mk ≥ 3(k = 1, ..., K) antennas and each receiver has a reconfigurable antenna with Mk preset modes. Stemmed from the existing DoF-oriented BIA (D-BIA) scheme, we propose a new BIA scheme to reduce the frequency of mode switching on the reconfigurable antennas while ensuring the same DoF as D-BIA. The proposed BIA scheme is named as switching-oriented BIA (S-BIA). Theoretical analysis shows that S-BIA needs less frequency of mode switching than D-BIA. Particularly, S-BIA offers remarkable mode switching saving when the antenna number Mk ≤ 3.

Hybrid cognitive radio (CR) networks can jointly utilize both licensed and unlicensed radio resources to gain better performance over pure licensed/unlicensed networks. This paper studies the system-level capacity of a hybrid cellular network that consists of licensed base stations (BSs) and unlicensed CR relays. Two limiting cases are considered, in which the CR relays are assumed to have infinite cache and no cache, respectively. We systematically derive the system capacity under different simplifying assumptions on interference and path loss. Our results reveal how the system capacity is related to various system parameters such as BS/relay density, bandwidth, power, and CR reliability. Such an insight can be useful for the planning of future heterogeneous cellular networks.

This paper presents an iterative carrier recovery (ICR) via soft decision metrics (SDMs) of low-density parity-check (LDPC) decoding in an LDPC coded quadrature phase shift keying (QPSK) system. It is crucial for wireless communication systems to work effectively, especially at low signal-to-noise ratios (SNRs). By maximizing the sum of the square of the SDMs of LDPC decoding with gradient oriented optimization of the objective function, it adaptively updates the carrier phase and frequency parameter accurately. The structure of the proposed scheme is also given, along with the phase ambiguity solution. Meanwhile, it is combined with the Costas loop tracking and the LDPC decoding feedback to eliminate residual carrier offsets. Simulation results indicate that the proposed ICR algorithm achieves good performance in an LDPC coded QPSK system under rather large carrier phase offsets, which is just within 0.1 dB of the ideal code performance at the cost of some moderate complexity. By the proposed scheme, a rate-1/2 LDPC coded QPSK system can even work at low bit SNR (Eb/N0) about 1-2 dB, which is useful in energy-limited wireless communications.

In this paper, we study a resource efficient coordinated beamforming design for the downlink of heterogeneous multiuser system. The objective function is formulated as maximizing the weighted sum per-cell resource efficiencies subject to per-user quality of service demands and per-cell transmit power constraints, which is hard to tackle due to the weighted sum-of-ratios form and the non-convex nature of the user rate. To solve this problem, we first introduce some auxiliary variables and transform it into an equivalent problem, which can be derived by the fractional programming and convex approximation method. Then, a resource efficient optimization algorithm is proposed to achieve the solution by exploiting geometric programming and second order cone programming. Numerical results verify the advantage of the proposed algorithm, and show that it converges to a stable point within a limited number of iterations.

In this paper, we propose a novel transceiver architecture at relay for multiple input, multiple output two-way relay channel (TWRC). This transceiver architecture consists of the analog beamforming in RF domain and the MMSE based digital processing at baseband, which is simplified as RF-MDP-MIMO architecture. Under the RF-MDP-MIMO architecture, the objective of this paper is to find the optimal relay transmit and receive beamformings that can achieve the boundary of the optimal capacity region with limited relay power. Specifically, by formulating the original optimization problem into two semidefinite programing (SDP) problems with rank-one constraints which can be effectively solved by the penalty function method, we can optimize relay transmit and receive beamformings alternatively. Then, the maximum achievable sum rate of TWRC can be obtained with the bisection method. Further, the achievable capacity region is realized. Numerical experiments are conducted to show that our proposed RF-MDP-MIMO architecture outperforms the RF-MIMO architecture in terms of the optimal achievable capacity region.

In multiple-input-multiple-output (MIMO) wireless communications, Space Shift Keying (SSK), Spatial modulation (SM) and Generalized Space Shift Keying (GSSK) are three novel MIMO modulation techniques, that can greatly reduce the complexity of MIMO systems. This paper investigates the physical-layer security in typical MIMO systems of these three modulations. We present an exhaustive analysis of secrecy rate for multiple antennas destination and eavesdroppers receivers. Without eavesdroppers channel information, both achievable secrecy rate and bit error rate (BER) are studied through joint modulated signal and jamming signal transmission. Our simulation results demonstrate that the proposed proactive source jamming method achieves improvement of secrecy rate and improved BER performance for multi-antenna users.

A novel method for three-dimensional (3D) imaging by combining a narrowband bistatic multiple-input-multiple-output (MIMO) radar with two uniform linear arrays and inverse synthetic aperture technique is presented. During a short coherent processing interval (CPI), the motion of the target can be equivalent to a synthetic uniform linear array, which, together with the two narrowband MIMO arrays, is capable to reconstruct the 3D image of the target. Compared with the one-snapshot narrowband MIMO 3D imaging using two rectangular arrays, the proposed method can achieve a significant saving on the number of antennas since the linear arrays and multiple-snapshot technique are employed. Considering the low resolution of the image via limited MIMO arrays, a compressive sensing (CS)-based method is proposed to improve the 3D resolution jointly. Finally, simulation results demonstrate the proposed method is effective.
