ABSTRACT:
A receiver system for a mobile telephone system comprises two or more antenna spaced a distance apart from each other greater than the wavelength of incident radiation, and a receiver. Each antenna is coupled to a respective receiver channel of the receiver, each receiver channel comprising an RF means for processing the received signals, and equaliser means for equalising and/or decoding the signals from the RF means. The equaliser means includes metric generating means for generating metric information which provides probability measures for a sequence of time intervals and for a multiplicity of possible states of the receiver within each time interval that the received signal has put the receiver into the respective states, and selector means for comparing the values of corresponding metrics from respective receiver channels for selecting received data from the receiver channel having the higher probability of accuracy.
