Column Reordering for Box-Constrained Integer Least Squares Problems
Stephen Breen, Xiao-Wen Chang
The box-constrained integer least squares problem (BILS) arises in MIMO wireless communications applications. Typically a sphere decoding algorithm (a tree search algorithm) is use…

Effects of the LLL reduction on the success probability of the Babai point and on the complexity of sphere decoding
Xiao-Wen Chang, Jinming Wen, Xiaohu Xie
The common method to estimate an unknown integer parameter vector in a linear model is to solve an integer least squares (ILS) problem. A typical approach to solving an ILS problem…
