摘　　要：A new method for allocating the transmitting power on the CDMA(code division multiple access)20001x forward link channel under the conditions of multipath and different rate is proposed. That is, based on the dependency that exists between the respective signal qualities of the pilot channel and traffic channels to allocate the forward link channels reasonably. The CDMA 20001x forward link exploits coherent demodulation with continuously transmitting pilot signals. Therefore the stronger the pilot channel, the less traffic power is required while the same transmission quality is maintained. On the basis of the laboratory test, the diagrams of the dependency are given in the paper, and then an optimal pilot signal quality,which minimizes the total transmitting power is found. This result can be used to maximize the capacity of CDMA 20001x system or improve the service quality at cell edge. It has significant meaning for the R&D of the practical system project.A new method for allocating the transmitting power on the CDMA(code division multiple access)20001x forward link channel under the conditions of multipath and different rate is proposed.
