Weighted Sum Rate Maximization for Full-Duplex Cellular Systems
Fangni Chen; Zhongpeng Wang
Recently, full-duplex (FD) transmission becomes an attractive option for increasing the throughput of wireless communication systems. Although the full-duplex technique has the potential to double the capacity of point-to-point wireless links, the strong self-interference at the front-end of the receiver created by the signal leakage from the transmitter antennas became a limiting factor. In this paper, we consider a cellular system where base station worked in full-duplex mode, i.e. it can transmit and receive at the same time and frequency and hence can simultaneously establish a downlink and uplink communication. We consider the transmit and receive filter design for weighted sum rate (WSR) maximization problem subject to individual power constraints at each node of the system. Numerical simulations shows that the sum-rate achieved by FD mode is higher than the sum-rate achieved by baseline HD schemes.
