Abstract:

In order to improve the multicast transmissions, a full-duplex (FD) receiver cooperation scheme is proposed in this paper. The transmitter sends one common message to two FD receivers, and each receiver forwards its received signals to its counterpart by the amplify-and-forward (AF) scheme. Due to the imperfect SI cancellation at the receivers and the AF scheme, the residual self-interference and the additive noise (RIAN) will be accumulated over time. First, this paper analyzes the equivalent channel model of the considered system as well as the the statistics of the accumulated RIAN. Then, with the forward decoding scheme, the corresponding achievable rates are derived, and the optimal power allocation is obtained via solving a max-min problem. In particular, one-side cooperation scheme (i.e., only one receiver forwards its received signal to its counterpart) is shown to be optimal to achieve the best system performance.
