Abstract [en]

The concept of Cooperative MIMO Relaying (CMIMOR)  has previously been introduced in order to allow terminals  with single antenna elements to take some advantage of the  MIMO techniques. In this paper we evaluate the capacity  of a radio network employing non regenerative CMIMOR  connections by explicitly taking into account the amount  of additional resources needed for relaying. The paper investigates  both a centralised and a decentralised resource  allocation algorithm. We show that with a tight resource  reuse, which is accomplished with the decentralised algorithm,  and high relay densities, the CMIMOR system  yields capacity figures superior to a single hop system employing  beamforming. The gains are expressed in terms of  average system capacity.
