CA 2620896

A channel estimator is configured to determine channel estimate parameters indicative of characteristics of a wireless communication channel based on a received signal comprising a known transmitted signal and a noise signal. The channel estimator is configured to apply, to the received signal, a frequency domain representation inverse of a combination of a known signal factor as a function of frequency and a noise factor.

Selon la présente invention, un estimateur de voie est conçu pour déterminer des paramètres d'estimation de voie indiquant des caractéristiques d'une voie de communication sans fil en fonction d'un signal reçu comprenant un signal transmis connu et un signal de bruit. Cet estimateur de voie est conçu pour appliquer, au signal reçu, une inversion de représentation du domaine de fréquence d'une combinaison d'un facteur de signal connu en tant que fonction de fréquence et d'un facteur de bruit.
