Closed-Form Error Analysis of OFDM-Based Selective Decode-and-Forward Cooperative Networks over Nakagami-m Fading Channels

In this paper, we investigate the error performance of OFDM-based selective decode-and-forward cooperative networks over independent but not identically distributed (i.n.i.d.) Nakagami-m fading channels, with integer values of parameter m. A closed-form expression for the bit error rate is derived, which is very important to guide the design of future wireless communication systems. Monte Carlo simulations are carried out to validate our analysis.
