Sistema OFDM, calculando a Taxa de BER em um canal AWGN.

Orthogonal frequency division multiplexing (OFDM) has been proved as the dominant modulation technique for 4G communication. The use of relaying improves the BER performance of OFDM system. In this paper the BER performance of AF relaying with averag
