hello..
i need basic idea about predisotortion...i m going to work with low pass filter at the input side and output side bandpass filter ..maily in my stsytem contains random intereger generator,qpsk modulato ,raise cosine filter then i waill apply awgn channel after that block i want to make response linear so i will add bandpass filter so please provide your knowledge with me in matlab..
which order filter?
type of filter?
FIR ya IIR?
