Capacity maximization on multi-relay MIMO cooperative system
Ying Lin, Suoping Li, Haiyan Chen, Duo Peng · 2016
Cooperative networking is used widely because it has advantages in terms of network capacity and transmission reliability upgrade. This paper presents an analytical study on channel capacity of amplify-and-forward (AF) relay system with multi-relays in multiple input multiple output (MIMO) system. The problem of resource allocation is studied in this paper and an algorithm of amplification matrix for each antenna of multi-relays is presented. Then we solved above problem using a global optimization method. Results of simulation show that proposed algorithm could greatly improve the channel capacity at little cost.
