Channel Error Correction Coding Theory And Its Dsp Implementation

With the development of communication continuously, also increases continuously to the request of the communication quality. As an important means to improve the security of information transmission, the error-correcting encoding technology has been attracted more and more attentions.Based on channel anti-jamming in millimeter instruction guided missile system, in this paper mostly made some theoretic analyses and simulation on the error-correcting encoding. And based on the communication characteristic of large velocity and small information and the thing about interference in channel, confirmed a coding project whichadapting to the system --connecting convolutional coding with interleaver. Anddesigned software program on the arithmetic, and a hardware circuit system to carry out this arithmetic with the common programmable fixed-point digital signal processor chip TMS320VC5410 and other peripheral chips, and made debugging at arithmetic using high speed serial communication circuit between DSP and PC.
