METHOD FOR PRE-FILTERING TRAINING SEQUENCES IN A RADIOCOMMUNICATION SYSTEM

摘要

The invention relates to a method for pre-filtering a training sequence in a radiocommunication system consisting in using an emitter in the form of an antenna device comprising several antenna systems, thereby making it possible to transmit the training sequences through a pre-filter to said antenna systems side for reradiation by the emitter. Estimation enabling to form the properties of radio transmission channels described by spatial correlations is formed. Said prefilter is dimensioned according to said correlations, thereby minimising the error value of a used algorithm for estimating the channel on a reception side.
