Improved K-best sphere detection for uncoded and coded MIMO systems

S Han, T Cui, C Tellambura - IEEE Wireless Communications …, 2012 - ieeexplore.ieee.org
The conventional K-best sphere decoder (KSD) keeps the best K nodes at each level of the
search tree. In addition to retaining the best K nodes, we also consider all the nodes whose …

Probability-distribution-based node pruning for sphere decoding

T Cui, S Han, C Tellambura - IEEE Transactions on Vehicular …, 2012 - ieeexplore.ieee.org
Node pruning strategies based on probability distributions are developed for maximum-
likelihood (ML) detection for spatial-multiplexing multiple-input–multiple-output (MIMO) …

An improvement of ZF/LR method in MIMO detection

M Abbasi, AA Tadaion… - 6th International …, 2012 - ieeexplore.ieee.org
In this paper, we propose a simple method which may enhance the performance of zero-
forcing (ZF) or lattice reduction (LR) algorithm in multiple input multiple output (MIMO) …

Soft-output extension of an SNR-adaptive sphere decoder for coded MIMO systems

S Han, C Tellambura - 2012 25th IEEE Canadian Conference …, 2012 - ieeexplore.ieee.org
In this paper, a list sphere decoding method based on an extension of the signal noise ratio
(SNR)-adaptive sphere decoder (SSD) is proposed to perform joint iterative detection and …
