Re: OFDM Under Fading
y is rayleigh fading, so it is multiplicative noise.
I do not compensate BPSK without OFDM, so I think the two results should be the same, but this did not occur
simulat qam awgn channel
I am facing the same problem for 16-QAM, also it does work for 4-QAM, please if you find the problem tell me, this will be kind of you
Re: OFDM Under Fading
below i inserted the code to read it and tell me where is the problem
clc
clear all
Esdb=0:5:50;
k1=0:length(Esdb);
Es=10.^(db/10);
sigma=sqrt(1/2);
snr=db;
NN=100000;
N=32;
Xn55=(rand(1,NN))>0.5; %%% Random data
Xn1=double(Xn55);
Xn5=(reshape(Xn1,N,[]))';
for...
when I simulated BPSK under Raleigh fading the simulated results was exactly as theoretical but when I use BPSK in OFDM system the result Untill 15dB like BPSK without OFDM but after that error floor occurred.
Can any one tell me what is the wrong???
PLZ help me
