Abstract: In this paper, the signal detection of orthogonal frequency division multiplexing with index modulation (OFDM-IM) in the rapidly time-varying channel is studied. Due to the inter-carrier interference, the conventional block detectors based on the successive… read more here.

DOI: 10.1109/tsp.2018.2824254
Abstract: Estimation of both cascaded and residual self-interference (RSI) channels and a new training frame structure are considered for full-duplex (FD) amplify-and-forward (AF) one-way relay networks with rapidly time-varying individual channels. To estimate the RSI and… read more here.

DOI: 10.1109/tvt.2022.3181801
Abstract: Due to the combined effects of different acoustic propagation, reflection patterns in different time-scale, time-varying underwater acoustic (UWA) channel generally exhibits hybrid sparsity, i.e., contains not only rapidly time-varying elements, but also stationary or slowly… read more here.
