Cooperative communication is a fourth generation novel scheme promising significant capacity and multiplexing gain in wireless communication.This paper derives the carrier to noise interference ratio (CNIR) and average bit error rate (BER) for orthogonal frequency division multiplexing (OFDM) based amplify and forward (AF) and decode and forward (DF) scheme over Nakagami fading channels.Numerical results are provided to show the significant improvement of DF in OFDM based cooperative communication due to same frequency offset and phase noise.
