We analyzed the performance of OFDM system regarding different channel. We analyzed the performance and showed the most suitable channel for OFDM communication system.
Moreover, we also applied different modulation scheme over OFDM system to show which modulation technique is more efficient for OFDM system. Here we used BPSK, QPSK, 16-QAM and 64-QAM modulation technique.
From our experiment we found that, among AWGN & the fading channels (Rayleigh & Rician),
AWGN channel has less BER and P(e) than others. So we can say that, for OFDM system,
AWGN channel is most suitable.
We also found that, in all environments BPSK shows better performance than QPSK, 16QAM &
64QAM. When modulation level increased, corresponding BER & P(e) also increased.
