“…Nonlinearity leads to various energy harvester models [7], [11], [12], new designs of modulation and input distribution [13]- [15], waveform [16], RF spectrum use [16], transmitter and receiver architecture [14], [16], [17] and resource allocation [11], [18], [19]. Of particular interest is the role played by nonlinearity on SWIPT signalling in single-carrier and multi-carrier transmissions [1], [13], [14], [16], [20]. In multi-carrier transmissions, it is shown in [16] that inputs modulated according to the Circular Symmetric Complex Gaussian (CSCG) distributions, improve the delivered power compared to an unmodulated continuous waves.…”
