IT++

Hi cristeab, Thank you for your reply,

but i am already settimg the OFDM Parameter and it works very well with AWGN.

But the question is that is the definition of my ITU Channel correct? and the second question is that when we use soft demodulation we usually give the channel coefficienct and here because of OFDM we have taken the FFT to be on frequency domain

also i have seen that the output length from the channel is adding 5 symbols more, is that because the process like convolution or something else thanks

or do you have another suggestion
