Judgement of error frames using frozen bits and its applications in decoding of polar codes

IET Communications, Volume 17, Issue 14, Page 1760-1772, August 2023., 2023
Based on the previous research, this paper proposes a strategy of using frozen bits to assist decoding. In the successive cancellation and the SC List algorithms, this strategy is used to identify wrong decoding in order to terminate decoding or pruning in advance.

Symbol detection using extreme learning machine network for MU‐SIMO systems

IET Communications, Volume 17, Issue 2, Page 183-196, January 2023., 2023
Abstract This paper focuses on symbol detection for a multi‐user single‐input multiple‐output (MU‐SIMO) uplink using supervised machine learning techniques. An extreme learning machine (ELM) is chosen as the equalizer at the receiver end due to its super‐fast learning ability and minimum training error.

A new design of channel denoiser using residual autoencoder

Electronics Letters, Volume 59, Issue 2, January 2023., 2023
A novel denoiser based on a residual autoencoder structure is proposed. The proposed denoiser speeds up training process and boosts the performance due to its structure effectively extracting compressed features. Simulation results show that this denoiser outperforms all the existing denoisers.
