Cooperative Communication for Spatial Frequency Reuse Multihop Wireless Networks Under Slow Rayleigh Fading

Free registration required

Executive Summary

Cooperative communication has been proposed as a means to increase the capacity of a wireless link by mitigating the path-loss, fading and shadowing effects of radio propagation. In this paper, the authors evaluate the efficiency of cooperative communication in large scale wireless networks under interference from simultaneous transmissions. Specifically, they consider tunable spatial reuse time division multiplexing and half-duplex decode-and-forward cooperative relaying on a hop-by-hop basis. They show that hop-by-hop cooperation improves the reliability of the transmissions particularly in the low-SINR or in the low-coding-rate regimes.
