A Lattice reduction (LR) aided receiver for multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems can achieve near ML detector performance. However, Performing LR for each subcarrier can result in a large complexity. To deal with this problem, a low complexity scheme for lattice reduction (LR) aided detection in the(More)
Transmit beamforming is a simple multiantenna technique for increasing throughput and the transmission range of a wireless communication system. The required feedback of channel state information (CSI) can potentially result in excessive overhead especially for high mobility or many antennas. This work concerns efficient feedback for transmit beamforming(More)
—In this article, we present a real-time full duplex radio system for 5G wireless networks. Full duplex radios are capable of opening new possibilities in contexts of high traffic demand where there are limited radio resources. A critical issue, however, to implementing full duplex radios, in real wireless environments, is being able to cancel(More)
