Abstract :
In the UHF frequency range, the received signal is the contribution of multi-reflected waves on different obstacles. A multisensor equalization scheme is proposed using a blind algorithm. GSM specification gives channel models for different environments. Those models are extended, with some assumptions, to a space diversity channel. This is used to evaluate and to compare several process. A discussion is made on the type of channel, on the data rate and on the number of sensors to use. Finally, the spatial equalizer is analyzed in term of beamforming
