Abstract


Wireless OFDM system is second name of modern communication, and international channel interference (ICI) is need to be suppressed to make communication easier and less noisy. In this paper we are working to reduce the bit error rate (BER). Now to reduce BER we have proposed the raised cosine windowing in the OFDM system with variable FFT size and we have found that the performance of system increases significantly.

Keywords


OFDM, ICI, Raised Cosine Window, FFT & BER
