Simultaneous information and power transfer with transmitters with hardware impairments [PDF]
2016 International Symposium on Wireless Communication Systems (ISWCS), 2016 We investigate the performance of a communication system with simultaneous wireless information and power transfer capabilities under non-ideal transmitter hardware. We adopt an experimentally validated additive noise model in which the level of the noise at an antenna is proportional to the signal power at that antenna. We consider the linear precoder
