Abstract The present invention discloses a method for implementing rapid channel convolutional coding by using impulse responce principle, and is characterized by that firstly, prestoring length of response state of coder, making simple O.I judgement for input bit, storing impulse responce to 1. ignoring impulse responce of O, then making cyclic iterative treatment to obtain convolutional code of channel. Said invention is applicable of convolutional coding treatment of all constraint lengths and all code efficients in the digital communication system. The adoption of channel convolution coding method can reduce lots of operational quantity, reducing load of DSP resource and can implement real time rapid processing in the third-generation mobile communication system.
