摘要：
In this paper, we present a new multiuser detection algorithm based on step ant colony optimization. This algorithm accelerates the process of search by setting the parameters of basic ant colony optimization appropriately and meanwhile introduces a strategy of jumping out of the local optimal solution, thus it can approach the minimum probability of error with great computation efficiency. Simulation results show that the proposed algorithm converges rapidly and provides good BER performance for cases where basic ant colony algorithms perform poorly.
