Brief description of the fight against - interference adaptive in a receiver multi - channels

摘要

Method of receiving and multipath receiver associated with a signal comprising at least a learning sequence is formed of known symbols, and at least one sequence useful. The method comprises the steps of: • reception, and transposing (601) of the signal received on each of the channels of the receiver by a signal equivalent baseband discretized, synchronization (602) of the signals discretized, • calculation (603) of a matrix of intercorrelation hexogene between the said at least a learning sequence and the signals are synchronized, the calculation (603) of an autocorrelation matrix rxx for the synchronized signals, the calculation (604) of a matrix h of a channel which exist on the basis of the matrix hexogene and of an autocorrelation matrix of the learning sequence rdd: h = rdxh rdd - 1, the calculation (605) of a matrix of correlation of the noise and interference: r = rxx - hrdx, and • use (606) of said matrix r in order to produce an equalization processing operation of multichannel systems on the signals are synchronized.
