摘要: We derive closed-form expressions for the achievable rates of a buffer-aided full-duplex (FD) multiple-input multiple-output Gaussian relay channel. The FD still suffers from residual self-interference (RSI) after application mitigation techniques. investigate both cases slow-RSI channel where RSI is fixed over entire codeword, and fast-RSI changes one symbol duration to another within codeword. show that can be completely eliminated in case when equipped with buffer while fast cannot eliminated. For fixed-rate data transmission scenario, we optimal strategy should adopted by source node maximize system throughput. verify our analytical findings through simulations.
