应用于空间调制的低复杂度A*检测算法
A Low Complexity A* Detection Algorithm for Spatial Modulation
摘要
Abstract
In order to solve the high complexity problem of A*detection algorithm,a novel detection algo-rithm is proposed to order the received antennas. Based on the existing A*detection algorithms,it adds the hierarchical order process of received antennas, which is more likely to include the optimal path for the branch of the first selected node in the A*detection algorithm and exclude the wrong nodes earlier. The al-gorithm can greatly reduce the number of nodes that need to be accessed when the tree search is per-formed . The complexity is reduced by about 73% ~89% compared with the maximum likelihood detection algorithm.关键词
