METHOD AND DEVICE FOR EVALUATION OF A RADIO SIGNAL WITH SPATIAL DIVERSITY IN THE RECEIVER

摘要

In order to evaluate a radio signal in a radio receiver, comprising an antenna device with several antennae elements (A1, ..., AM), each of which delivers a received signal (U1, ..., UM),a number N of first weighting vectors w<(k,1)>, w<(k,2)> ,which represent a selection of the eigen vectors for the time-determined spatial covariant matrix, for a user station (MSk) are determined. The symbols contained in the user signal Ik, obtained by the formation of a product of the form SWU are assessed. W is the M x N matrix for the first weighting vectors, S is a selection vector with N components and U is the vector for the received signals (U1, ..., UM). The selection vector is cyclically fixed in the working phase. A device for the evaluation of a radio signal, comprises, amongst others, a memory element (10) for the storage of N weighting vectors for each one same sender (MSk) and a beam formation network (1) with a control input of the selection vector (S).
