thanks aya, i didnt implement the zero pad before the serial to parallel..
how can i implement it?
as well as, the zero pad removal..
and is x=ifft(parallel_data); enough as a command for the IFFT block..
parallel_data is the modulated data converted to parallel..
thank you.
hi all,
what is the proper way of implementing the ifft in an ofdm using qpsk?
i have this qpsk modulation code using Gray coding but when i insert the ifft before the command of adding the noise, and an fft before demodulation, the BER is rising to ~ 0.5.
