Abstract
An improved space-time MOE blind multi-user detection algorithm based on RLS was proposed, which is got through expanding the time-only MOE blind multi-user detection algorithm to space-time domain. The structure of multi-user detector was analyzed, and the iteration equation of weight was deduced. This algorithm can avoid using direct eigenvalue decomposition at each iterations, so its operation complexity reduced. The simulation shows that the improved algorithm has better performance to combat multiple access interference than the time-only MOE blind multi-user detection algorithm.
