OFDM Channel Estimation Along with Denoising Approach under Small SNR Environment using SSA

open access: yesJournal 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
