4psk
M=4的PSK通信系统进行蒙特卡罗仿真
仿真BPSK和4PSK调制信号在高斯信道下的性能,并与理论分析结果相比。
(1) 画出两条性能曲线,一条是根据理论平均错误概率画出,另一条是仿真曲线;
(2) 程序的基本流程:信源产生信息比特、调制、将调制信号送入信道(产生高斯白噪声的程序)、接收端检测、将检测结果与信源原始信息比较计算误符号率和误比特率;
(3) 在给定信噪比下,第二步需多次重复,以得到一个平均错误概率;
(4) 信噪比范围:BPSK(0dB – 10dB),4PSK(0dB-14dB),间隔是1dB 也可在BER=10-6左右终止。
(5) 信噪比计算 SNR=10log(Es/N0)=10log(REb/N0).

压缩感知程序源码 BCS
压缩感知程序源码,Blind compressed sensing (BCS)不需要在采样和恢复阶段预先知道稀疏基。源码对于研究压缩感知前沿具有很好的借鉴意义。(The fundamental principle underlying compressed sensing is that a signal, which is sparse under some basis representation, can be recovered from a small number of linear measurements. However, prior knowledge of the sparsity basis is essential for the recovery process. Blind compressed sensing (BCS) avoids the need to know the sparsity basis in both the sampling and the recovery process. That is, BCS aims at recovering an ensemble of vectors, all sparse under the same unknown basis, given small number of linear measurements of these vectors.
