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...
The distribution of the received signal power ?? of a multiple-input multiple-output system, with the associated 2 ?? 2 complex Wishart matrix having n degrees of freedom, is investigated under the channel inversion power allocation scheme. Exact closed-form expressions are derived for the probability density function and the cumulative distribution function of ??. The analysis covers systems with...
