Performance Analysis of COOPERATIVE OFDM Systems

Kavita Narayanan , Bilal Shafeek

Orthogonal frequency division multiplexing (OFDM) is becoming the chosen modulation technique for wireless communications. OFDM can provide high data rate, large spectrum efficiency with sufficient robustness to radio channel impairments. Cooperative diversity in wireless communication is a promising technique to mitigate multi-path fading, which results in a fluctuation in the amplitude of the received signal. This work combines the features of both OFDM and cooperative communication thereby achieving a better system performance in terms of the bit error rate.
