Abstract

We consider the problem of optimal power allocation to a user transmitting on a fading channel. The our Is using some specific, convolutional or turbo code. The cost function to be minimized is the bit error rate. The user needs to satisfy an average power constraint We And that the optimal power policy is code and fading distribution dependent and can be significantly different from the commonly considered policies e.g, water filling and (truncated) channel inversion. The gain In BER can be substantial.
