摘要
An overall SIR estimate is based on a weighted-average of different SIR estimates, wherein the weights are chosen to minimize the mean-square-error (MSE) of the overall SIR estimate. Alternatively, the overall SIR estimate is based on a selection from among the different SIR estimates, based on the expected reliability of each SIR estimate. The expected reliability of each SIR estimate may be based on the current format of the transmitted signal and/or a prior estimated SIR level.
