Abstract

In this paper, a lead compensator is proposed for compensating round-trip delay of direct-sequence code-division multiple-access (DS-CDMA) cellular mobile radio systems. Furthermore, in addition to the delay compensation, a disturbance rejection filter is designed to minimize the effect of uncertain noise and interference to track a desired signal to interference and noise ratio (SINR). The two-step power control design is achieved by the H₂ optimal approximation theory using the genetic algorithm. To confirm the performance of the proposed method, several simulation results are given in comparison with other methods.
