Performance analysis of antenna correlation on land mobile satellite based MIMO systems by Yuan LIN, Yuan-zhi HE, Jing-chao WANG, Han HAN

“…The joint effect of spatial correlation and shadowing of channels on the performance of land mobile satellite MIMO system was analyzed.With the help of contour integral,residue theorem and integral of special functions,closed-form approximations of the outage probability (OP) and the average symbol error rate (SER)were derived.The Monte Carlo simulations results were illustrated through several examples in order to assess the impact of correlation coefficient,the number of antenna and different modulation mode on the performance.It shows that although channel correlation and shadowing degrade system gain,significant performance gains can be obtained by multi-satellite MIMO systems compared to relevant single-input single-output (SISO) ones.…”

Video compression and encryption coding scheme based on zero tree by ZHANG Rong, ZHU Zhi-chao, YIN Dong, LIU Zheng-kai

“…According to the security of the scalable video stream,an integrated video compression-encryption scheme was proposed.The scheme chooses wavelet transform as the compression platform,encrypts the zero-tree symbol during the zero-tree generation process to guarantee the security of the video.Furthermore,a multiple levels encryption was proposed to satisfy different consumers’ requirement.It is proved that the scheme kept the scalability of the encoding,has high security,and small impact on compression efficiency,so it is suitable for real-time video transferring on the network.…”

Design of a subnonsecond Gauusisan pulse generator based on the RF transistor by YANG Feng1, XUE Quan2, CHAN Chi-hao2

“…A simple and low cost subnonsecond Gaussian pulse generator was developed using RF transistor,chip resistors,and chip capacitors.The generator utilized a differential circuit to convert signal from the FPGA into a pairs of positive and negative pulses,which was then used to control the “on” and “off” states of the RF transistor,thus generating an ultra-short pulse through the charging and discharging of the capacitor.The measured results shows that output waveform have 0.8ns pulse duration and morn than 1.8V from an input wave of 25MHz repetition rate.Good agreement between the measured and calculated results is achieved.This circuits is suitable for microwave integrated circuits（MIC）.…”
