Practical Hybrid Beamforming for Millimeter Wave Massive MIMO Full Duplex With Limited Dynamic Range

Full Duplex (FD) radio has emerged as a promising solution to increase the data rates by up factor of two via simultaneous transmission and reception in same frequency band. This paper studies novel hybrid beamforming (HYBF) design maximize weighted sum-rate (WSR) single-cell millimeter wave (mmWave) massive multiple-input-multiple-output (mMIMO) FD system. Motivated practical considerations, we assume that multi-antenna users base station (BS) suffer from limited dynamic range (LDR) noise due non-ideal hardware an impairment aware HYBF approach is adopted integrating traditional LDR model mmWave In contrast conventional schemes, our also considers joint sum-power per-antenna power constraints. A interference, self-interference (SI) optimal allocation scheme for uplink (UL) BS presented satisfy The maximum achievable gain multi-user (MU) system over fully digital half duplex (HD) with different levels numbers radio-frequency (RF) chains investigated. Simulation results show outperforms HD only few RF at any level. advantage having amplitude control analog stage examined, additional becomes evident when number small.
