Signal processing in passive radar with multi-user MIMO-OFDM signal
EURASIP Journal on Advances in Signal Processing, 2022 In this paper, we propose a signal processing method in passive radar using the multi-user (MU) multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) signal as the illuminator of opportunity.

A spatial interference minimization strategy for the correlated LTE downlink channel [PDF]
, 2010 In a downlink transmission, users can benefit from the high capacity gain achieved by transmitting independent data streams from multiple antennas to multiple users sharing the same physical time-frequency resources.

Differential Downlink Transmission in Massive MU-MIMO Systems [PDF]
IEEE Access, 2019 In this paper, a differential downlink transmission scheme is proposed for a massive multiple-input multiple-output (MIMO) system without explicit channel estimation. In particular, we use a downlink precoding technique combined with a different encoding scheme to simplify the overall system complexity. A novel precoder is proposed, which, with a large

Effect of Unpredictable Interference on MU-MIMO Systems in HetNet
IEEE Access, 2018 In this paper, we investigate the outage probability of a multiuser multiple-input multipleoutput (MU-MIMO) system in the heterogeneous network (HetNet) in the presence of unpredictable interference (UI) from coexisting ad hoc systems.

Channelization Issues with Fairness Considerations for MU-MIMO Precoding Based UTRA-LTE/TDD Systems [PDF]
, 2008 In a pre-coded Multi User Multiple Input Multiple Output (MU-MIMO) system, the channelization can be done either by using any of the two basic access techniques, namely Orthogonal Frequency Division Multiple Access (OFDMA) and Space Division Multiple ...
