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

OFDM Channel Estimation Along with Denoising Approach under Small SNR Environment using SSA
Journal of Communications Software and Systems, 2022 —In this paper, a de-noising approach in conjunction with channel estimation (CE) algorithm for OFDM systems using singular spectrum analysis (SSA) is presented. In the proposed algorithm, the initial CE is computed with the aid of traditional linear
