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.

分辨率增强函数,一个独立的Matlab函数，用以实现滑块控制的分辨率增强。(Resolution enhancement function, a separate Matlab function for the slider control to achieve the resolution enhancement.)
