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

ANALYSIS OF SPATIAL-TIME CHARACTERISTICS OF A RADIO LINE WITH MULTIPATH WITHIN 5G TECHNOLOGY
Information and Telecommunication Sciences, 2020 Background. As a result of the reflection of rays from buildings, from the surface of the Earth or from horizontal boundaries between different layers of the atmosphere, multipath effects occur that cause fast fading, which affects the quality of service.
