We propose leveraging one-dimensional expanded Hybrid codes (1-D E-Hybrid codes) for two-code keying (TCK) in spectral amplitude coding (SAC) optical code division multiple access (OCDMA) networks. The proposed system can utilize all codes and provide a larger code size. The numerical results demonstrate that the 1-D E-Hybrid codes for TCK outperform the existing 1-D approaches, and the data transmission rate can achieve 2.5 Gbps. Then, the proposed system provides the fiber failure recover scheme on the system architecture. The proposed system can maintain the transmission and efficiency with fiber failure recover scheme when the fiber failure is suddenly happen.

Throwing-mine detection is a typical problem of low RCS (radar cross section) targets detection in heavy clutter, in which the high false alarm rate is a difficult problem. Classical CFAR (Constant False Alarm Rate) detection algorithm only utilizes the image contrast characteristics, in the case of low SNR (Signal to Noise Ratio), a large number of false alarms generates. In order to further reduce false alarm rate, CFAR-IHP (Constant False Alarm Rate-Internal Hermitian Product) detection algorithm is proposed in this paper. CFAR-IHP is based on CFAR and target azimuth coherence characteristic, therefore, we first get the sub-aperture image sequence to extract target azimuth information by the sub-aperture processing algorithm for SAR image. Lastly, based on Ku-band SAR data, we use CFAR-IHP (Constant False Alarm Rate-Internal Hermitian Product) algorithm to detect the targets, experimental results show that the method further eliminate the clutter and the azimuth coherence helpfully reduces the false alarms.

A stacked Yagi antenna excited by a modified magneto-electric (ME) dipole is presented. The ME dipole is composed of a horizontal planar dipole and metallic vias which work as magneto dipole and the antenna is simply fed by a coaxial feed without using a balun. Simulated results indicate that the proposed antenna operates from 48 GHz to 74 GHz (S11≥-10dB). Stable radiation patterns with low back radiation and gain of over 10dBi can be observed in the whole operating band. This antenna element yields advantages of wideband, high gain and low-cost fabrication.

Recently, it has been proven that retransmission based on Network Coding (NC) can greatly improve the performance of wireless networks with broadcast erasure channels. However, network coding also introduces additional delay at the both sending and receiving sides, resulting in the decline of the Quality of user Experience (QoE). In this paper, we consider the users' waiting time and the decoding delay as the performance metrics and then propose MixCode, a NC-based loss recovery method, to improve the delay performance in heterogeneous wireless networks. MixCode incorporates Opportunistic Network Coding (ONC) with Random Linear Network Coding (RLNC), where a NC packet can be decoded by simply XORing operation at some destinations, but by Gaussian elimination at other destinations. Simulation results show that our proposed algorithm can efficiently reduce both the waiting time and the decoding delay in comparison with the existing NC-based schemes.

This paper describes the implementation of a realtime and easy-to-use mobile system based on accelerometer for the monitoring of Parkinson's tremor. About 70% of Parkinson's disease patients were starting with tremor symptoms, which usually occur on patients' fingers or hands. Unfortunately, there is no any real-time mobile monitoring system for Parkinson's tremor which can be used almost anytime, anywhere. This work mainly focused on the implementation of a mobile application of previous proposed novel accelerometer-based method for the real-time assessment of Parkinson's tremor. Besides providing the diagnosis of tremor's severity, this tool also analyzed the variation of the tremor behavior. As the result, people faking the tremor behavior can be detected from the variation of the analysis.

Through-Wall Imaging Radar (TWIR) can reconstruct targets which are concealed behind the wall, so it is highly desired in antiterrorism, hostage situations and other fields. To detect, track and locate personnel targets behind the wall, the TWIR must have the ability of high data frame rate and fast imaging speed. In this paper, we analyze the imaging algorithm for two dimensional multiple input multiple output (MIMO) TWIR. To satisfy the real-time requirement of TWIR applications, we design a parallel realization method based on TMS320C6678. Experimental results show that this parallel method can adequately fulfill the real-time requirements.

In this paper, a kind of leaky-wave beam scanning antenna based on NRD waveguide was studied. The structure of NRD waveguide is changed by replacing dielectric strip with magnetic biased ferrite material. Radiation is formed slotting one of the metallic plates sandwich the ferrite strip. When the biased magnetic is turned, the beam can sweep in the NRD propagation plate.

This paper presents a low-temperature co-fired ceramic (LTCC) equalizer, providing the maximum attenuation of 12 dB over 2 to 6 GHz. In order to reduce the size, a LTCC composite right-left handed (CRLH) resonator and a simplified composite right-left handed (SCRLH) matching network were analyzed and utilized to form the proposed passive equalizer. The insertion loss of the equalizer is less than 1.25 dB, while the return loss is better than 12 dB at 2-6 GHz band. The final size of this equalizer is 18×7×0.302 mm3, a quarter of that of traditional one.

In this paper, a intelligent and fast two-dimensional constant false alarm rate (CFAR) processor to perform adaptive threshold target detection is presented. It employs a composite approach based on the well-known cell averaging CFAR (CA-CFAR) and ordered statistic CFAR (OS-CFAR) processors. In this case, any masking effects in multi-target situations can be avoided without increasing the computation complexity. Besides, utilization of binary integration results in a higher detection performance. The simulation results verify the validity of the algorithm.
