Channel Capacity For Single Branch Receivers Operating In Generalized Fading Scenarios

In this paper, we provide closed-form expressions for the average channel capacity (ACC) of single branch receivers operating in generalized fading channels. The expressions are obtained in terms of the well-known Meijer's G-functions, which are easily implemented in the most popular computing softwares. For comparison purposes, the capacity of additive white gaussian noise channels is depicted and, as expected, it outperforms those proposed here. In addition, it is shown that, for any given fading condition, the Nakagami-m ACC defines regions of capacity, appearing as either lower bound or upper bound in the generalized fading scenarios. © 2007 IEEE.215218Lee, W.C.Y., Estimate of channel capacity in Rayleigh fading environment (1990) IEEE Trans Veh.
