Adaptive multisensor receiver for mobile communications

This paper describes a digital receiver for radiomobile communications. The adaptive filter is a purely spatial filter. The used criterion is the minimisation of a mean square error between the array output signal and a reference signal. The reference signal is generated using the demodulator results. No learning sequence is required. The algorithm is digitally implemented and it uses a direct matrix inversion algorithm. The performance study, using simulation and experimental results, shows tracking properties, jammers cancelling and multivath correction.
