Function File: h, st = rcosfir(R,nT,rate,T,filterType) ¶

Implements a cosine filter or root cosine filter impulse response

R Roll-off factor

nT scalar vector of length 2 such as N = (nT(2)-nT(1))*rate+1

T symbol rate

filterType ’normal’ or ’sqrt’

h impulse response

st sampling interval

Example:

h = rcosfir(0.2,[-3 3],4,1,’sqrt’);
