In the viewpoint of engineering project,we study some key techniques related to HF data transmission under the condition of extremely low R SN , design a scheme of BCH coding and decoding integrated with interleaving,finally realize the scheme on DSP hardware platform,target of resisting random and burst error and achieved
Two improved methods for the video transmission through network are presented: the first method changes the burst error in the network into statistically independent error, using convolution and interlaced technique on the packet encode;
In this paper, (15,11) system cyclic code is taken by way of example for auto-cor- rection single error and continuous four burst error. A design method of cyclic code and its practical circuits are given. This method can also be used in (N-K) system cyclic code to realize the correction of (N-K) burst errors.
This paper presents an algebraic decoding algorithm to correct burst error in binary BCH code and deduces the equations as well as solutions. This algorithm for BCH(31,21 ) burst and the known algorithm for BCH(31, 21) random, combined with the methods of vector and look-up table, can avoid the operation of multiplication in normal algorithm and can be fast realized by means of software.
