摘　　要：基于格形图预测算法原理,建立使用二进制码元模拟功率控制事件的系统模型,设计了一个格形状态图,根据其状态相似性定律调节发射功率.该算法可用于宽带码分多址WCDMA(wideband code division multiple access)系统的功率控制仿真中.结果表明,它能有效实现WCDMA系统功率控制过程,相对传统功率控制算法能提高系统容量,减少系统仿真时间.The principle of a trellis-based algorithm was described. The algorithm was theoretically analyzed, and a simulation model was built. The power control events were modeled by a sequence of O＇s and 1＇s by devising a trellisbased prediction method that adjusted the transmitting power strength according to the degree of similarity between the prediction and the actual state of power control events. of the WCDMA system. The system capacity was increased The proposed algorithm was applied to the power control , and the simulation time was reduced by using the proposed algorithm in simulations
