Signaling Over Two-User Parallel Gaussian Interference Channels: Outage Analysis

ABSTRACT:

This paper presents an outage analysis for a 2-user parallel Gaussian interference channel consisting of 2 sub-channels. Each sub-channel is modeled as a two-user Gaussian interference channel with quasi-static and flat fading. Each users use single-layer Gaussian code-books and maintain a statistical correlation between the signals transmitted over the underlying sub-channels. When joint decoding (JD) is performed at the receivers, setting minimizes the outage chance, regardless of the worth of the signal-to-noise ratio (SNR). It's shown, however, that if the receivers treat interference as noise (TIN) or cancel interference (CI), the value of optimum approaches 1 as SNR goes to infinity. Motivated by these observations, we let below JD and underneath TIN and CI and compute the outage chance in finite SNR, assuming that the direct and crossover channel coefficients are freelance zero-mean complicated Gaussian random variables with possibly completely different variances. Within the asymptote of huge SNR and assuming the transmission rate per user is , it is shown that the outage chance scales like below both TIN and CI, while it vanishes at least as quick as underneath JD. This paper is concluded by extending a number of the results to a 2-user parall- l Gaussian interference channel with an arbitrary variety of sub-channels.
