MULTI-STEP PREDICTIVE POWER CONTROL IN CDMA SYSTEM AND THE METHOD THEREOF

摘要

The invention provides a power control method of the mobile station considering the delay time through the multi-step prediction, channel sample vector a _j , estimated channel sample , the transmission power predicted value stage, p-channel samples considering the delay time using the channel prediction filter for initializing the vector a _j updating a, sample the channel vector a _j p steps (p sample time (unit: PCG)) based on the estimated channel sample after step for calculating, on the basis of the power control operation of the previous time that the mobile station transmit power prediction step after p step, the operation after the prediction step p-channel sample predictive power transmission and mobile predicted on the basis of the received SIR step for calculating, the predicted reception SIR with a predetermined threshold SIR _TH includes the step of generating a PCB for controlling the mobile station power on the basis of the phase, the comparison result of comparing. ; According to the present invention, a p-channel operation is independent of the sample vector is a multi-step to prevent error propagation problem in predicting cumulative.
