A communications system is disclosed comprising a plurality of mobile stations and an improved base station for receiving signals from said mobile stations and decoding information-bearing signals transmitted therefrom. An antenna comprising antenna elements disposed around a support structure receives signals transmitted from the plurality of mobile stations and generates output signals from each antenna element. Convertors amplify, filter and convert signals from each of the antenna elements into a corresponding number of converted signals for processing. Storage devices temporarily store a number of samples of the converted signals. Processors iteratively process and reprocess the stored samples successively to decode the information from each of the mobile stations in turn. The processing provided by the processors identifies from the stored samples an information symbol transmitted by one of the mobile stations thereby decoding the information-bearing signal, and subtracts values dependent on the identified information symbol from the stored samples thereby reducing interference between the just-decoded signal and the signal to be decoded at a subsequent iteration.
