- Abstract
In order to solve the high complexity problem of A* detection algorithm, a novel detection algorithm 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 algorithm can greatly reduce the number of nodes that need to be accessed when the tree search is performed. The complexity is reduced by about 73% ~89% compared with the maximum likelihood detection algorithm.
