ABSTRACT:
The estimated power levels that are used to estimate a signal-to-interference ratio (SIR) are filtered so as to minimize the mean-square error (MSE) of the estimated power estimates. First order infinite impulse response (IIR) filters are used to filter both the signal power estimates and the noise power estimates. Optionally, estimates of the average signal power and average interference power are filtered using Weiner linear prediction filters. The SIR estimates are suitable for use in a transmission channel that includes fading as well as interference, and are suitable for use in BPSK, QPSK, and other modulation systems.
