Abstract Due to the excellent broadcasting characteristics of radio signals, simultaneous wireless information and power transfer (SWIPT) can transmit both energy, provide users with stable supply. Wireless channel has openness, which will lead leakage in SWIPT system. It is one research hotspots industry ensure secure transmission system where there are differences energy information. This pap...

Relying on the propagation of modulated radio-frequency (RF) signals, we can achieve simultaneous wireless information and power transfer (SWIPT) to support low-power communication devices. In this paper, proposed a unary coding based SWIPT encoder by considering practical M-QAM. Markov chains are exploited for characterising coherent binary source modelling generation process symbols. Therefor...
