Channel Estimation for Orthogonal Time Frequency Space (OTFS) Massive MIMO
Wenqian Shen, Linglong Dai, Jianping An +2
Orthogonal time frequency space (OTFS) modulation outperforms orthogonal frequency division multiplexing (OFDM) in high-mobility scenarios. One challenge for OTFS massive MIMO is d…
Beamspace Channel Estimation for Millimeter-Wave Massive MIMO Systems with Lens Antenna Array
Linglong Dai, Xinyu Gao, Shuangfeng Han +2
By employing the lens antenna array, beamspace MIMO can utilize beam selection to reduce the number of required RF chains in mmWave massive MIMO systems without obvious performance…
Near-Optimal Linear Precoding with Low Complexity for Massive MIMO
Linglong Dai, Xinyu Gao, Shuangfeng Han +2
Linear precoding techniques can achieve near- optimal capacity due to the special channel property in down- link massive MIMO systems, but involve high complexity since complicated…
Low-Complexity Soft-Output Signal Detection Based on Gauss-Seidel Method for Uplink Multi-User Large-Scale MIMO Systems
Linglong Dai, Xinyu Gao, Xin Su +3
For uplink large-scale MIMO systems, minimum mean square error (MMSE) algorithm is near-optimal but involves matrix inversion with high complexity. In this paper, we propose to exp…
Full Duplex Networking: Mission Impossible?
Shuangfeng Han, Chih-Lin I, Linglong Dai +2
Mobile traffic is projected to increase 1000 times from 2010 to 2020. This poses significant challenges on the 5th generation (5G) wireless communication system design, including n…
