[Communication-Mobile] Alamouti DL : 0: 主函数Alamouti(Nr,max_snr,max_err_symbol,symbol_per_frame) 调用函数QpskMapping(psudo_bit_sequence)－－二进制数据到QPSK信号的变换调用函数RayleighCH(Nr,Nt)－－瑞利衰落信道模拟仿真示例： Alamouti(1,12,20,24) 说明： 1.2根发射天线、1根接收天线 2.最高信噪比为12dB，即仿真范围为0dB到12dB 3.在每个信噪比条件下,误符号数超过20即停止该信噪比条件下的仿真 4.每一帧数据为24个QPSK符号综合仿真函数SimAlamouti(max_snr,max_err_symbol,symbol_per_frame) 具有一根接收天线系统的SER性能与二根接收天线的系统SER性能比较 SimAlamouti(12,20,24) 参数说明： 1.max_err_symbol的取值直接影响了仿真的精度：取值越大，精度越高，误符号率曲线也更平滑；但需更长的仿真时间 2.一般max_snr小于15dB，程序中snr为信号噪声功率比 3.本程序仿真时未考虑帧与帧之间，信道衰落系数的相关性，因此symbol_per_frame一定程度上表征了信道相关时间的大小，即在symbol_per_frame个QPSK信号发送时间内，信道衰落系数是不变或缓变的，而在下一帧数据中，信道衰落系数可以认为已变成另一值 4.本程序假定在接收端已通过信道估计获得信道衰落系数-ALAMOUTI performs Monte-Carlo simulation and estimates Bit Error Rate (BER) of Alamouti Scheme [1] over Rayleigh channel. The scheme presumes 2 transmit (Tx) and arbitrary number of receive (Rx) elements. If Rx=1 (one receive element) ALAMOUTI is transformed to the order 2 transmit diversity scheme with Maximum Ratio Combining (MRC). The modulation format is MPSK with arbitrary order M which can be controlled by user.

[Industry research] Efficient-BER-computation-of-LDPC-coded-SC_MRC-sy DL : 0: Abstract—Selection combining cascaded with maximum-ratio combining (SC/MRC), which is particularly useful when site diversity is available, combined with low-density parity-check (LDPC) codes is able to combat the effects of fading. The biterror rate (BER) expressions of uncoded SC/MRC and SC/MRC with LDPC codes over an independent and identically distributed Rayleigh-fading channel are derived based on the Gaussian approximation approach. These expressions are also applicable to the selection combining and maximum-ratio combining as special cases. The derived expressions are in good agreement with simulation results and approach the density evolution (DE) thresholds. These expressions are able to achieve a significant reduction in computational time with a reasonable accuracy for analyzing the BER performance as compared to simulations and DE.

[Program doc] 1687-1499-2014-112 DL : 0: In this paper, an Alamouti-coded decode-And-forward protocol with optimum relay selection for three-user one destination cooperative communications is investigated. Particularly, we design the new protocol that allows the source node retransmitting the signal to the destination node at the same time as the relay node forwarding the received signal to the destination node with an Alamouti coding scheme. We exploit the cooperative maximum ratio combining technique (C-MRC) at the destination for combining a multiple copy of received signals.
