Distributed temporal precoding with a novel power allocation scheme in cooperative systems

In cooperative systems, precoding techniques can be utilized through temporal continuous symbols transmitted by the source node, which is termed as distributed temporal precoding (DTP). In this paper, we propose a novel power allocation scheme combining with DTP and the adaptive modulation and coding technique, which is based on the greedy algorithm and designed with practical modulation and coding schemes. Simulation results demonstrate that the proposed power allocation scheme achieves higher throughput than equal or water-filling power allocation schemes.
