Abstract: In some orthogonal frequency division multiplexing (OFDM) systems, a number of OFDM symbols form one subframe and consecutive subframes may be allocated to different users. The power estimation and the gain adjustment need to be… read more here.

Abstract: In this paper, we introduce a reservoir computing (RC) structure, namely, windowed echo state network (WESN), for multiple-input-multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) symbol detection. We show that adding buffers in input layers is able to… read more here.

DOI: 10.1109/twc.2021.3051317
Abstract: In this paper, we investigate online learning-based MIMO-OFDM symbol detection strategies focusing on a special recurrent neural network (RNN) – reservoir computing (RC). We first introduce the Time-Frequency RC to take advantage of the structural… read more here.
