Near-MLD MIMO Detection Based on a Modified Ant Colony Optimization

摘要

In wireless multiple-input multiple-output (MIMO) systems, maximum-likelihood detection (MLD), is impractical because it requires an exhaustive search. This letter formulates MIMO MLD as a pathfinding problem shows it can be solved using a modified ant colony optimization. Simulation results demonstrate that the proposed method achieves near-MLD performance with low computational complexity.
