This paper investigates destination-aided simultaneous wireless information and power transfer (SWIPT) for a decode-and-forward relay network, in which massive multiple-input multiple-output antennas are deployed at relay to assist communications among multiple source-destination pairs.
During relaying, energy signals are emitted from multiple destinations when multiple sources are sending their information signals to relay.
With power splitting and unlimited antennas at relay, asymptotic expression of harvested energy is derived.
The analysis reveals that asymptotic harvested energy is independent of fast fading effect of wireless channels; meanwhile transmission powers of each source and destination can be scaled down inversely proportional to the number of relay antennas.
To significantly reduce energy leakage interference and multipair interference, zero-forcing processing and maximum-ratio combing/maximum-ratio transmission are employed at relay.
Fundamental trade-off between harvested energy and achievable sum rate is quantified.
It is shown that asymptotic sum rate is neither convex nor concave with respect to power splitting and destination transmission power.
Thus, a one-dimensional embedded bisection algorithm is proposed to jointly determine the optimal power splitting and destination transmission power.
It shows that destination-aided SWIPT are beneficial for harvesting energy and increasing sum rate.
The significant sum rate improvements of the proposed schemes are verified by numerical results.
