摘要

This paper proposes time-reversal based power division multiple access (TRPDMA) to enhance achievable sum rate (ASR) in dense multi-path environment. The proposed TRPDMA uses power division to distinguish multiple users while time-reversal division multiple access (TRDMA) uses backoff factor. The analytical channel model is derived to calculate ASR and ergodic ASR (EASR) with circular symmetric complex Gaussian random values (CSCG RVs) which are expressed in the form of channel impulse response (CIR). For performance metrics, ASR, EASR, outage probability (OP) and complexity are evaluated to compare with non-orthogonal multiple access (NOMA) and TRDMA.
