Estratégias de Transmissão para uma Rede com Canal Retransmissor Multidirecional

A multiway relay channel (mRC) which is widely employed in the literature is extended to represent a larger num- ber of practical scenarios, such as a vehicular network (VANET). For the proposed system, g-mRC, three transmission strategies are presented and analyzed in terms of maximum effective rate, for different numbers of users. Numerical results show that the best strategy is the one in which all users transmit simultaneously in the multiple access phase. Each strategy presents an optimal number of users which maximizes the effective rate. The system model and the transmission strategies presented can be useful in several practical scenarios.
