SIGNAL-TO-INTERFERENCE + NOISE RATIO ESTIMATOR AND METHOD, MOBILE TERMINAL HAVING THIS ESTIMATOR

摘要

The SINR (signal-to-interference+noise ratio) estimator comprises a low-pass filter (66) to filter a varianceσκcomputed from the received pilot symbol amplitude to obtain an estimated varianceσκwith a reduced bias, wherein the low-pass filter has an adjustable coefficient and the estimator comprises an electronic controller able to adjust the value of the adjustable coefficient according to the number of pilot symbols received during a timeslot.
