基于MATLAB的QPSK通信系统仿真源码，信道误码率等(MATLAB-based simulation of communication systems QPSK source, channel bit error rate)

This Matlab script finds the frequency offset effects in the orthogonal frequency division multiplexing (OFDM)and its effects on the bit error rate (BER). A reference paper is also included.

基于维特比译码算法的BPSK解调方式，survivor_state是一个矩阵，它显示了通过网格的最优路径，这个矩阵通过一个单独的函数metric(x,y)给出，这个算法既能用于硬判决译码也能用于软判决译码。 (BPSK demodulation method based on viterbi decoding algorithm, survivor_state is a matrix, the optimal path of it shows through the grid, the metric matrix through a separate function (x, y), the algorithm can not only used for decoding hard decision can also be used to the soft decision decoding. )
