METHOD OF FILTERING A RADIO COMMUNICATION SIGNAL, COMPRISING THE CALIBRATION OF AN ADAPTIVE SYSTEM, AND CORRESPONDING RADIO COMMUNICATION DEVICE

Document Type and Number:

WIPO Patent Application WO2005018183

Kind Code:

B1

Abstract:

The invention relates to a method of filtering a useful radio communication signal. According to the invention, one such method involves the use of a digital adaptive filter. The inventive method comprises a step involving the calculation of coefficients of the aforementioned digital adaptive filter, such as to provide a periodic update of said coefficients. The initialisation of the calculation step takes account of a set of coefficients specific to each radio communication device, which were pre-stored in a memory element provided for said purpose.
