Abstract

Cooperation between physically separated wireless nodes can achieve the high signal-to-noise ratio (SNR) diversity gains characteristic of multi-antenna arrays. Simulations indicate that such gains are still achieved for SNRs in the range of practical interest for several applications. Cooperation further yields SNR gains in addition to diversity gains. In contrast to diversity, the SNR gains are affected by the choice of inter-node distances. Such SNR gains are quantified in this paper via a geometry-inclusive error analysis. The notion of geometry-inclusive SNR gains is developed to facilitate geometry-based comparisons of cooperative strategies.
