| Abstract: | In the paper, an approach of SIR estimation for CDMA2000 1x system is introduced. The algorithm is based on the statistics characteristic of the signal. With a sample and common system model, the deciding value of the receiver output is counted firstly, then the mean and variance of the deciding value are calculated. So, the SIR of the receiver outputs is estimated. further more some results of SIR estimation and the performance of closed loop power control by the computer simulation are presented. Finally the availability of the SIR algorithm in the CDMA2000 1x system is proved. |
