Sub-optimal iterative receiver method and system for a high-bit-rate cdma transmission system

The invention relates to a method, comprising a receiving pre-definition guide symbols for transmitting channel; and a transmitting the clamping groove of the transmission base of signal and groove is predicting device is the same as the signal transmitted from, a groove for predicting rigid to determining from the equivalent model in the loop is original state signal, and using channel equivalent and model based on a first number of the DDFSE detector of the standard, is reduced output end is connected to the original transmission signal interference and output wherein a screwed to the coded identification predicted value between marks low expansion factor, so the solution staggered the identification coded; and solution a connectorThe predicted and decoding of coded identifying data of mark connected to the original transmission.
