Abstract: Due to the fading of the channel,the energy harvester converts the harvested electromagnetic wave energy into a power source for transmitting wireless signals again,and its power has random dynamic characteristics. Aiming at the wireless communication environment with Nakagami-m channel fading,linear radio frequency energy harvesters combining with multi-slot "harvest-storage-use" and "harvest-use" schemes to realize EH are proposed. The effective throughput of the "harvest-storage-use" EH scheme and the average bit error rate of binary digital coherent and incoherent demodulation of the "harvest-use" EH scheme are studied and analyzed. The simulation results show that the wireless communication adopting the "harvest-storage-use" strategy has the optimal number of time slots to achieve the best effective throughput,while the wireless communication adopting the "harvest-use" EH scheme should use a small number of time slots to balance the bit error rate and communication delay.

Key words: energy harvesting, Nakagami-m, effective throughput, bit error rate
