Low Detection Symbol Algorithm for MIMO Systems with Big Number of Antennas

Abstract:

Low detection algorithm on symbol-flipping (SF) is presented, which obtain the Maximum Likelihood performance in MIMO system with big number of antennas. Through a simulation spatial search analysis, we reveal that SF procedure, which is based on local search. Based on the analysis, we develop a novel detector algorithm with simple SF for MIMO systems. Further, we proposed to employ several SF steps whose initial points are in a set of random initial solutions chooses the best SF as the solution.
