The invention relates to the channel error-correcting coding technique which can protect the Woven convolution code error-corrector in the TD-CDMA system. The invention replaces the Turbo code in present channel coding with the Woven convolution code error-corrector and encoder which uses a series of encoders to replace the internal and external encoders of step-connected code. The Woven convolution code uses two steps of coding structure, while the iterated decoding structure is used for decoding. Since the simple convolution component code and the paralleling decoding structure are used in the invention, the time delay of decoding and the operational complexity are reduced markedly. So the Woven convolution code more fits the high-speed high-real time service to improve the property of system compared to the Turbo code.
