Method for processing signal in communications system having plurality antennas
First Claim
1. A method for processing signal in a communication system having a plurality of antennas, comprising the steps of:
- (a) extracting a first signal mostly including a specific signal, and a second signal mostly including a signal other than the specific signal, from a signal received at the plurality of antennas;
(b) calculating an autocovariance matrix of each of the first and second signals;
(c) dividing at least any one of the calculated autocovariance matrices into a diagonal component and a non-diagonal component, to separate the matrix into matrices of the components;
(d) calculating a weighted value for the specific signal by using the separated autocovariance matrices; and
, (e) applying the weighted value to a transmission, or reception signal related to the specific signal, and forwarding a signal having the weighted value applied thereto.

Abstract
The present invention relates to an adaptive algorithm and device for the same, for calculating a weight vector to be applied to an adaptive array antenna system, suggesting an adaptive algorithm suitable for calculating an autocovariance matrix of signal vectors of signals received from antennas before despreading in a known channel code, and an autocovariance matrix of signal vectors of signals received from antennas after being despread in the known channel code. Particularly, the calculation is carried out with the autocovariance matrix of the signal vector before the despread divided into diagonal components and non-diagonal components.
