北大高慧璇版《应用多元统计分析》第3章3多元正态总体参数的假设检验MATLAB编程源码(Applied Statistical Analysis)

a simulation example of the passe bande filter

frequency expander. Matlab code for expander.When x is a vector, this function adds L-1 after each element of x. When x is a matrix, each column of it treated as vector and expanded L fold. SQUARE-ROOT RAISED-COSINE PULSE: h=sr_cos_p(N,L,alpha) This function generates a square-root raised-cosine pulse of length N+1. There are L samples per symbol period. alpha is the roll-off factor.
