A simple cooperative protocol for interference channel using path selection
Shengnan Chen, Zhiguo Ding, Bin Chen, Xuchu Dai · 2010
In this paper, a simple protocol of cooperative transmission is developed by combining path selection with non-orthogonal amplify-forward (NAF) for the two-user single-antenna interference channel. Three time slots are enough for the proposed protocol to ensure each pair to achieve diversity gain of two, whereas existing cooperative protocols require four time slots. Analytic results, such as outage probability and the achievable diversity-multiplexing tradeoff (DMT), and Monte-Carlo simulation are provided to demonstrate the performance of the proposed protocol.
