METHOD AND DEVICE FOR SELECTING A RECEIVER IN A MULTI-ANTENNA COMMUNICATION DEVICE AS A FUNCTION OF THE ENVIRONMENT

摘要

The invention relates to a method and device for selecting a receiver in a multi-antenna communication device as a function of the environment. The communication device comprises antennas (A_Q) which are adapted to receive a signal from a transmission channel. The device also comprises two receivers, of which only one exploits the spatial structure of the signal, and means for calculating a variable as a function of the spatial correlations of the samples of the signal, such as to produce an estimate of the gain that can be obtained using the receiver that exploits the spatial structure of the signal. The receiver is selected as a function of said estimate.
