DOI: 10.1109/lsp.2022.3229641
Abstract: In simultaneous transmit and receive (STAR) phased array systems, suffering from the multi-dimensional cross-coupling strong self-interference (SI), the radio frequency (RF) front-end of receive array is severely saturated. Against this issue, we present a transmit… read more here.

DOI: 10.1109/tvt.2022.3141597
Abstract: In this paper, we address the problem of channel estimation in a single cell massive multiple-input multiple-output (mMIMO) system with distributed antenna arrays (DAA) under the availability of limited pilots. Specifically, we propose to use… read more here.

DOI: 10.1109/twc.2022.3208436
Abstract: Large array systems use a massive number of antenna elements and clever precoder designs to achieve an array gain at the user location. These precoders require linear front-ends, and more specifically linear power amplifiers (PAs),… read more here.
