Power Control in Interference Channels With Class A Impulse Noise.

In this letter, we consider optimal power allocation, with respect to sum capacity, for an interference channel affected by additive independent Class A impulse noise. The probability distribution of the sum of a Gaussian and a Class A distributed variable is derived, and the result is exploited to derive the sum capacity of an interference channel with independent Class A distributed impulse noise. Moreover, we show that the optimal power allocation strategy for the Class A interference channel can differ significantly from the solution to the commonly used additive white Gaussian noise interference channel.
