In the dual-polarized channel, the power amplifier (PA) energy efficiency is decreased by cross-polarization discrimination (XPD) effect which introduces cross power leakage and then reduces the BER performance of polarization modulation (PM). Therefore, an XPD compensation algorithm based on PM for the PA energy efficiency improvement is proposed. Firstly, the effect of energy efficiency caused by...
In dual-polarized channel, the BER performance of polarization modulation (PM) can be decreased by cross-polarization discrimination (XPD) effect which can introduce cross power leakage. Therefore, a XPD compensation algorithm for PM is proposed. Based on the analyses about the effect of XPD on PM, the compensation factor is obtained by the channel state information. Then by compensating the state...
