New approaches to improve a WCDMA SIR estimator by employing different post-processing stages

For effective control of transmission power in WCDMA mobile systems, a good estimate of signal-to-interference ratio (SIR) is needed. Conventionally, an adaptive SIR estimator employs a moving average (MA) filter (Yoon <i>et al</i>., 2002) to encounter fading channel distortion. However,...
