| 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 tracted more and more attentions. In many practical communication, The error is often mixed wrong. To deal with such mixed errors want a design that is independent random errors can be corrected or the burst error-correcting codes. To solve this problem, often usd cascade method.This paper mainly analysis the channel error-correcting encoding of the interference shortwave communication systems. Using correct coding technology we research technology of communication system.This paper mainly analysis the channel error-correcting encoding of the interference shortwave communication systems. Used BCH encoding method , Then channel coding problem, put out the (7, 4) linear block codes, cyclic codes and BCH intertwined concatenated coding method. This cascade intertwined codec also made several detailed theoretical analysis. In random Channel and many unexpected mistakes, these were compared for several channel coding error rate between not weaving, and weaving .Had proven uses interweaves the cascade technology to be allowed greatly to reduce channel the error rate. The paper did some particular theory research of BCH codes interleaving. On this base, the paper did software simulation to test the performance of the channel coding. BCH come interleavedConcatenated coding solution using shortwave noise of a good communications program. |
