The Matlab code investigates the harmful effects of high power amplifier on ofdm signals. It is imagined that the amplifier destroy the amplitude of the transmitted signal due to saturation and has no effect on the signal phase. The model is acceptable for solid state amplifier to some extend.

You have to bring the range of generated as the first parameter of randi(). That is you have to replace randi(N-numOfZeros,numOfSym,M) with randi((M,N-numOfZeros,numOfSym). Also you have to change randi(M,N-numOfZeros,numOfSym) to randi([0 M-1],N-numOfZeros,numOfSym) as qammod() function does not take index from 1, rather from 0.

hello,I can't run this code in matlab R2017b even if I changed the function randint to randi, can you help me?

hi , how can w include the input power back off effects on OFDM can you suggest some sugegestions

Swee-Ann Teo

it's an awesome piece of work, but could u extend it to include AM-PM?

Hello every body pease replace the code num2str(N) with num2str(N*GI) in line 161

hai,

it's very useful for ofdm researcher.....
make it use...
