In order to resolve the problem of multi-user jamming and near-far effect in the multi-user detection,an improved ant colony algorithm is proposed for multi-user detection in synchronous CDMA system. By analyzing the work flow of ant colony algorithm and the operating principle of multi-user detection in CDMA system,this paper expounds the improvement procedures of ant colony algo-rithm.The simulation is performed for improved ant colony algorithm by using MATLAB.The simulation results show that the improved algorithm has better performances,compared with traditional methods.
