SI_PSO

说明：  8单径瑞利信道中的四发四收V-BLAST： (1) 请设计一种具体的导引辅助的信道估计方法，用Simulink进行仿真，测量16QPSK调制时的误码率性能。画出比特信噪比与信道估计均方误差的关系曲线，画出比特信噪比与误码率的关系曲线。 (2) 计算所设计方案的频谱效率是多少，单位为bit/Hz/s。(8 Single-Path Rayleigh Channel Four received four V-BLAST: (1) Please design a specific guide-assisted channel estimation method, using Simulink simulation, measurement 16QPSK modulation BER performance. Draw-bit signal to noise ratio and channel estimation mean square error curve, draw-bit signal to noise ratio and bit error rate curve. (2) calculate the design of spectrum efficiency is the number of units of bit/Hz/s.)

说明：  16psk格雷映射的误码率仿真,已通过matlab仿真，绝对好用( Bit Error Rate for 16-PSK modulation using Gray modulation mapping you can know 16psk modulation and gray modulation and apply them in your program)
