A Linearithmic Time Algorithm for a Shortest Vector Problem in Compute-and-Forward Design
Jinming Wen, Xiao-Wen Chang · arXiv (Cornell University) · 2016
We propose an algorithm with expected complexity of $\\bigO(n\\log n)$ arithmetic operations to solve a special shortest vector problem arising in computer-and-forward design, where $n$ is the dimension of the channel vector. This algorithm is more efficient than the best known algorithms with proved complexity.
