Abstract:
1. A method of estimating a signal-to-interference ratio (SIR) of baseband signals which are received and processed by a data demodulator to provide demodulated symbols to a SIR estimator, the method comprising: (a) the SIR estimator receiving the demodulated symbols from the data demodulator; (b) the SIR estimator estimating the average signal power of the demodulated symbols as a function of a median based average power value m (c) the SIR estimator estimating the average effective interference power of the demodulated symbols; and (d) the SIR estimator calculating the SIR by dividing the estimated average signal power of the demodulated symbols by the estimated average effective interference power of the demodulated symbols.
