METHOD FOR ESTIMATING SIGNAL-TO- NOISE RATIO IN A TELECOMMUNICATION RECEIVER AND APPLICATION OF SAID METHOD FOR CONTROLLING A TRANSMITTER

摘要

The invention concerns a method for estimating a signal-to-noise ratio, in particular digital, received by a radio communication receiver. Said method is characterised in that it consists in estimating separately the signal and the noise and in filtering (36, 44) separately the signal (Eb) and the noise (N0) before carrying out the division (40) of the signal from the noise. The noise filtering is for example of the statistical type, whereas the signal filtering is of the low-pass filtering type.
