- Abstract
An energy-harvesting decode-and-forward cooperative system over correlated Rayleigh fading channels is investigated. Simultaneous wireless information and power transfer (SWIPT) technology is employed at the relay to improve energy efficiency. To overcome the spatial correlation among the transmit antennas, precoding spatial modulation (PSM) is formulated. The average bit-error probability (ABEP) upper bound is derived and it matches closely with the Monte Carlo simulation results. The influence of the parameters, such as the power-splitting factor and transmit correlation coefficient, on system performance is studied. The results show that the proposed PSM-SWIPT system can achieve better ABEP performance than SM-SWIPT, space shift keying-SWIPT and multiple-input-multiple-output-SWIPT systems under the same spectral efficiency.
