Time division duplex (TDD) pre-equalized orthogonal frequency division multiplexing (OFDM) systems can save system resources by omitting pilot symbols. Meanwhile, a new problem arises that the timing error would degrade system performance, because this error cannot be revised in the absence of pilot symbols. The paper investigates the impact of timing error on the receiver's bit error rate (BER) performance for TDD pre-equalized OFDM systems using phase-shift keying (PSK) modulation. The analytic binary PSK (BPSK) and quadrature PSK (QPSK) BER expressions of ideally and nonideally pre-equalized OFDM systems are obtained, in multipath Rayleigh fading environment. The corresponding simulations verify the analytic expressions. Compared with the theoretical system performance bound, the performance of ideal and nonideal pre-equalized BPSK systems entail loss of 1 dB and 3 dB respectively when the normalized timing error is 1/8. When it is 1/4, the performances of both systems degrade severely. At the same time, the gap between them diminishes. In that case, timing error becomes dominant among those elements which would affect systems performance. The higher the modulation order adopted, the more sensitive to timing error the system performance becomes.

The aim of this paper is to determine the probability that the decision variable of a maximum search based direct sequence synchronization procedure exceeds also a signal detection threshold set by the generalized likelihood ratio detector. The required distribution is derived independent of the signal presence or absence. Neither has the investigated code phase be the correct one. The derived novel probability is required in the analysis and threshold setting of synchronization processes of systems that have uncertainty on the existence of the signal. These include all random access type systems. Also other required probabilities, like the more familiar probability that the correct bin is the maximum, are determined using the same asymptotic analysis method. The analyzed results are compared to the simulated ones. It can be concluded that the analyzed results predict very well the points where the probability is high, near to one. These are typically the points that the system designers like to know.

An analytical model of two-layer retransmission scheme is proposed for CDMA systems in which selective repeat automatic repeat request (ARQ) is used at the radio link protocol (RLP) layer and n-channel stop-and-wait hybrid ARQ at the medium access control (MAC) layer. The retransmission mechanism in the RLP has considerable amount of delay associated with it, which might not be able to sustain real-time communications with strict delay requirements. Retransmissions done at a lower layer, such as the MAC, enhance the performance of the system. We show how the joint reliability varies with respect to the maximum retransmission number of RLP layer and MAC layer. We also consider when soft packet combining at the MAC layer of the receiver is supported, which effectively lowers the frame error rate (FER). Compared with the RLP layer ARQ used in IS-99, the two-layer retransmission scheme shows shorter packet transmission delay and lower packet error rate. The results show that it can offer faster and more reliable communication.

Hanly and Yates proposed algorithms for combined power and cell control that were proved as the optimal solution to combined power and cell control if such a solution exists. Anpalagan and Sousa proposed a combined power and cell and rate control algorithm with the main idea of interference balancing between base stations. They proposed an algorithm which was empirically proved to yield the optimal solution in terms of the average transmit bit energy of the system. A mathematical proof is given that shows the optimality of the algorithm toward interference balancing of the system.

A novel signal recognition and signature code acquisition (SR/CA) method is proposed for DS-SS systems with frequency offset. Based on existing SR/CA methods, the new soft SR/CA method introduces double decision thresholds and an automatic frequency control (AFC) loop. The performance analysis and double thresholds set criteria are discussed. Numerical results show that the soft SR/CA method provides better detection performance, while false alarm probability hardly increases.

We present a novel approach for analyzing the SER of linear MIMO zero-forcing and minimum mean squared error receivers in correlated Rayleigh fading environments with fading correlation at the transmitting and, for the first time, receiving antenna array. Specifically, we make use of certain complex Gaussian integrals for calculating the moment generating function of the subchannel SNR statistics. Using a well-known integral representation of the Gaussian Q function, it is then shown that the SER can be expressed in terms of a single integral. The novel approach is exact, non-asymptotic in the number of antenna elements, and unifies and complements existing partial solutions, thereby comprising the practically important case of multiuser smart antenna applications with optimum combining algorithm at the base station. Moreover, we present concise asymptotical expressions for the high SNR regime that allow for a simple assessment of the influence of fading correlation on the SER performance.

A wideband 16/spl times/32 MIMO channel sounder has been developed for the 5.8 GHz band. The paper reports on a series of measurements with the purpose of investigating both temporal and spatial aspects of channel changes in a number of widely different indoor environments. The measurements are carried out using two planar arrays of monopoles. The results include statistics on capacity, coherence bandwidth, and Doppler spreading for the various measurement scenarios.

We discuss designing M-phase spreading sequences of Markov chains optimal in terms of bit error probabilities, where M = 3, 4,... We consider SSMA (spread spectrum multiple access) communication systems using M-phase spreading sequences of Markov chains and give a necessary and sufficient condition that the limit of variance of the real part of the normalized MAI (multiple-access interference) for such systems becomes independent of the phase shifts. We also give a necessary and sufficient condition that the distribution of the real part of the normalized MAI is Gaussian. Based on these results, we discuss the optimum 3-phase and Q-phase (quadratic-phase) spreading sequences of Markov chains in terms of bit error probabilities in SSMA communication systems.

We study the power allocation problem in wireless multiple-input multiple-output (MIMO) systems adopting QAM modulation. In addition to the total power constraint, two additional practical constraints are included in our study. Firstly, the quality of service (QoS) specification is expressed in terms of required BER for each subchannel. Secondly, only a few discrete constellation sizes are available for signal modulation. We analyze the power allocation problem for such systems, and introduce a new performance index, so-called throughput-improvement-to-power-increment ratio (PITIR), to reveal the underlying idea of the strategy. We then propose a power allocation algorithm for maximizing the data throughput given total power budget. The proposed algorithm is simple and efficient for implementation, and it achieves almost the same data throughput performance and total power consumption as a previously published scheme. In addition, the proposed algorithm can make use of computational results obtained in earlier transmissions, and this reduces the overall computation load.

In a multiple input multiple output (MIMO) context, we present, in this paper, a space-time bit interleaved coded modulation (STBICM) system combined with a space-time spreader called linear precoding. We propose a practical low-complexity receiver structure performing iteratively space-time detection and channel decoding. The novelty lies in the linearity of the space-time detector which consists of an MMSE MIMO PSIC equalizer and a linear deprecoder. Spectral efficiency and diversity can easily be tuned while keeping a feasible receiver. In the case of independent flat Rayleigh fading, simulation results show that such a system exploits both spatial diversity and capacity provided by the multi-antenna system.
