Fast BCH decoding method applied to remote command extraction

In order to ensure the reliable transmission of remote control information in noisy channel,combined with the traditional BCH code algorithm,a fast BCH(63,56) decoding method according with the packet telecommand control is designed based on the look-up table method in this paper.It is relatively simple and easy for hardware implementation.Meanwhile,the design,simulation and verification are also given based on FPGA.The simulating results prove that this encoding and decoding design has the characteristics of fast computation and less resource occupying.And it can be applied to the packet telecommand control communication.
