Radio frequency (RF) energy harvesting provides wireless sensors with permanent and convenient energy supply. In this paper, we study the statistics of harvested RF energy of secondary wireless sensor over quasi-static fading channels. We also investigate the performance of secondary sensor transmission with harvested RF energy. Specifically, assuming that the sensor uses all the harvested RF energy for transmission, we derive the exact statistics of received signal-to-noise ratio (SNR) over Nakagami fading channel. We also investigate the statistics of received SNR under a primary interference constraint. The statistics are applied to performance evaluation in term of outage probability and average error rate. Selected numerical results are presented to illustrate the mathematical formulation.
