FIELD: information technology.
SUBSTANCE: signal samples transmitted from several access terminals are received; demodulated output signals of the service signal transmission channel are compared with a threshold value, where the service signal transmission channel contains at least one of the following channels: a reverse rate indicator (RRI) channel, a data request control (DRC) channel and a data source control (DSC) channel; if the demodulated output signals of the service signal transmission channel exceed the threshold value, the service signal transmission channel is decoded through a detector based on a method of maximum likelihood of characters; decoded bits of the service signal transmission channel are used to restore the service signal transmission channel; data of the service signal transmission channel are nullified from the received samples; and after the said nullification, the samples are processed to obtain traffic data transmitted by at least one access terminal.
EFFECT: increased noise suppression efficiency.
