Multiuser detection, which can efficiently mitigate the multiple access interference, is a hot topic nowadays for CDMA systems. In this research, a mutated ant colony optimization (MACO) algorithm is proposed by introducing the mutation mechanism to the ACO algorithm and is applied to multiuser detection. Compared with the ACO multiuser detector, the presented MACO multiuser detector can lead to quicker convergence and avoid local optima with almost the same computational complexity. Via computer simulations in CDMA communication system, it is shown that the performance of MACO multiuser detector in reducing the near-far effect and bit-error rate is much better than that of ACO multiuser detector and is also close to or even equal to the performance of optimal multiuser detector. |
