摘要：
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 multirelays 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.
