The golden code in asynchronous distributed networks with relay selection
Lu Ge, G. J. Chen, Jonathon A. Chambers · 2012
In this paper, we propose an effective scheme to achieve asynchronous distributed transmission with a linear dispersion algebraic space-time code, namely the Golden Code, over a two-hop MIMO relay channel. We realize multi-relay selection transmission with maximum-minimum and maximum-mean multi-relay selection strategies to improve the bit error rate (BER) performance. In addition, we adopt full maximum-likelihood (ML) decoding and sphere decoding (SD) as the detection approach within the asynchronous relay network. Simulation results based on end-to-end bit error rate confirm the efficacy of the approach.
