Statistical resource decoupling in random access interference channel

We study how the presence of stochastic fading channels can create statistical decoupling between two interfering flows in a basic interference network. We show that under some conditions of interference and power allocations, the sum throughput of the network with fading channels is higher than the sum throughput for Gaussian collision channel with identical average channel conditions. This higher throughput is a result of fading channels, which sometimes decouples the two flows allowing them to receive successfully even if the interfering flow is simultaneously active.
