Abstract

We consider an underlay massive Multiple-Input Multiple-Output (MIMO) cognitive radio system possessing only statistical knowledge for the primary system, where the Secondary Transmitter (ST) operates in a spatial multiplexing mode, while the secondary receiver employs zero-forcing detection. Assuming that ST is capable of energy harvesting, we present the optimal power allocation for the multiple transmitted data streams as well as the effective number of transmit antennas meeting both the maximum allowable outage threshold for the primary system and a constraint related to the ST energy consumption effectiveness. The tradeoff between transmit-and-harvest antennas at ST and the average channel capacity of the secondary system are analytically discussed. Representative numerical and simulation results corroborate the effectiveness of the proposed scheme and presented analysis, while some useful engineering insights are provided.
