DOI: 10.1109/jsac.2025.3531532
Abstract: Efficient implementation of massive multiple-input-multiple-output (MIMO) transceivers is essential for the next-generation wireless networks. To reduce the high computational complexity of the massive MIMO transceiver, in this paper, we propose a new massive MIMO architecture… read more here.

DOI: 10.1109/tit.2017.2736560
Abstract: The generalized degrees of freedom (GDoF) characterization of the symmetric $K$ user interference channel is obtained under finite precision channel state information at the transmitters (CSIT). The symmetric setting is where each cross channel is… read more here.
