Fixed-complexity Sphere Encoder for Multi-user MIMO Systems
Manar Mohaisen, KyungHi Chang
In this paper, we propose a fixed-complexity sphere encoder (FSE) for multi-user MIMO (MU-MIMO) systems. The proposed FSE accomplishes a scalable tradeoff between performance and c…

Lattice Reduction Aided Precoding for Multiuser MIMO using Seysen's Algorithm
HongSun An, Manar Mohaisen, KyungHi Chang
Lenstra-Lenstra-Lovasz (LLL) algorithm, which is one of the lattice reduction (LR) techniques, has been extensively used to obtain better basis of the channel matrix. In this paper…

Improved Achievable Rates for Regularized Tomlinson-Harashima Precoding in Multiuser MIMO Downlink
Bing Hui, Manar Mohaisen, KyungHi Chang
Tomlinson-Harashima precoding (THP) is considered as a prominent precoding scheme due to its capability to efficiently cancel out the known interference at the transmitter side. Th…
