BRD_ESRNet and SRS‐Based Channel Estimation
Journal of Electrical and Computer Engineering, Volume 2023, Issue 1, 2023., 2023 In wireless communication, the channel function estimated commonly has errors due to the influence of noise, so traditional channel estimation methods cannot accurately estimate the real channel function. Aiming at this problem, we propose a channel estimation method that combines sounding reference signal (SRS) remapping with the deep‐learning network

Journal of Electrical and Computer Engineering, Volume 2023, Issue 1, 2023., 2023 Nowadays, multicarrier modulation schemes are being widely used in wireless communication system than single‐carrier modulation techniques. Single‐carrier modulation schemes are less capable of dealing with multipath fading channels than multicarrier modulation schemes, which results in lower spectral efficiency.

International Journal of Satellite Communications and Networking, Volume 40, Issue 2, Page 133-147, March/April 2022., 2022 We present the feasibility study of performing multiple spacecraft per aperture ground operations by using low‐cost software‐defined baseband. The telemetry link shows minimal BER degradation. The telecommand link shows modulation index distortion and out‐of‐band emissions that necessitate a software‐defined signal pre‐distorter.
