CE-OFDM-CDMA Phase Modulation for 5G System [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2021 In the present work, we propose a novel modulation scheme for 5G wireless communication system. Our contribution is to combine PM-OFDM (Phase Modulation Orthogonal Frequency Division Multiplexing) and CDMA (Code Division Multiple Access) to exploit their

Incremental rate maximisation power loading with BER improvements [PDF]
, 2010 This paper aims to maximise the rate over a MIMO link using incremental power and bit allocation. Two different schemes, greedy power allocation (GPA) and greedy bit allocation (GBA), are addressed and compared with the standard uniform power allocation (
