To solve the base station pilot power allocation problem in WCDMA network, a solution based on immune clone algorithm was proposed. The mathematical model of base station pilot power allocation problem was expounded, the framework of immune clone algorithm was given, and simulation experiments were done to validate algorithm. Simulation result shows that the proposed algorithm can obtain the approximate optimal solution of base station pilot power allocation problem in large networks with an acceptable running time, and has the advantages of aood anolieation value.
