FIELD: technology for receiving and decoding data of various users in multi-access communication system with code channel expansion.
SUBSTANCE: usage of auto-regressive smoothing of soft solutions about trustworthiness of receipt of code symbols by multi-user detector, their following decoding with restoration of the whole code word, auto-regression smoothing of restored soft solutions with following soft limitation of hyperbolic tangent function, and also estimation of complex envelope curve at each iteration, provides for increased receipt quality in multi-access communication system with code channel expansion, in other words, increased interference resistance of receiver, increased capacity of communication system, reduced cost of base station of system with code channel expansion.
EFFECT: increased interference resistance of signal receipt in multi-access communication system with code division of channels due to iterative combined detection and decoding of data of various users.
