Performance analysis of energy beamforming with a multiple-antenna access point (AP) and a single-antenna user over line-of-sight (LOS) channels is not readily available. In this paper, we thus consider Rician channels between the AP and the user and derive the distribution of the received signal-to-noise ratio (SNR) via the distribution of the product of two independent non-central Chi-square variables. We also derive exact expressions for outage probability (OP), ergodic capacity (EC), throughput optimal energy harvesting time and bit error rates (BERs). Several approximate or asymptotic expressions are also derived. Finally, simulation results are presented to verify our analytical results.
