摘要 在码分多址(CDMA)通信中, 多用户检测是抑制多用户干扰的有效方法. 结合群智能和禁忌搜索算法的优点, 提出了一种新的群禁忌搜索(S TS)多用户检测方法, 通过粒子群的并行禁忌搜索, 使算法具有很强的全局寻优能力. 仿真实验证明, 该方法具有较好的误比特性能、抗远近效应能力和多项式计算复杂度. In this paper, tabu search(TS) and swarm intelligence were combined to develop a novel multi-user detection technique, named Swarm-Tabu Search(S-TS) algorithm. Simulation showed that the S-TS multi-user receiver had excellent bit-error-rate(BER) and anti-near-far performance as well as low computational complexity.
