Abstract

This letter addresses the problem of OFDM analytical error rate evaluation over fading channels under nonlinear amplification. We obtain approximate solutions to the problem over Nakagami-m and compound gamma-log-normal fading radio channels. In the latter case, two approximations are used for the composite gamma-log-normal distribution. One of them is approximation by the generalized k distribution, and the other technique reduces the problem to that over Nakagami-m fading.
