cognitivel
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.
