| Popis: | Consider a two-hop interference relay network with K multi-antenna transmitters and receivers, and a single multi-antenna relay. The relay employs amplify-and-forward (AF) strategy. The direct links between transmitters and receivers are assumed to be present. A distributed power allocation scheme is sought via the alternating direction method of multipliers (ADMM) algorithm at the transmitters under individual transmit power constraint to assign the minimum power to each encoded data stream such that a signal to interference plus noise ratio (SINR) target is met. Numerical results demonstrate that the proposed distributed scheme achieves the centralized solution. |
