DISPOSITIFS D'ESTIMATION DE CANAL RADIO ET DE DEMODULATION

摘要

The invention concerns an adapted filter (5) producing observations of a reference vector (r) of W successive samples of a signal formed by adapted filtering of a signal (Y) received through a radio propagation channel with a pilot spread code (Cr). A processing is performed in said adapted filter output to estimate the parameters representing the propagation channel, including specific vectors (Vk) of a self-correlating matrix of the reference vector and the specific associated values ( lambda k). Said parameters can be used to perform coherent demodulation of the signals received through other logic channels sharing the same physical propagation channel.
