Abstract

In this paper, the outage probability performance of interference-limited wireless relay networks is investigated. The considered wireless relay networks consist of several cooperation units (CUs, defined as one source and destination node pair with a relay node associated to it). All source nodes transmit their own signals simultaneously and the relay node in each CU then forwards the received signal to the destination node, causing co-channel interference at both the relay node and the destination node in each CU. The outage probability of the link between the source node and the destination node in a CU over Rayleigh slow-fading channels with interference is analyzed for the decode-and-forward (DF) relaying strategy. The end-to-end outage probability in a CU and the signal-to-interference-plus-noise ratio (SINR) distribution are derived in closed form. Numerical results indicate the effect of interference.
