摘要
为了保证遥控信息在有噪信道中可靠传输,结合传统的BCH码算法,根据查表法设计了一种符合分包遥控标准的快速BCH(63,56)译码方法。该译码方法相对简单,便于硬件实现,并通过FPGA对其进行设计、仿真及验证,结果证明,此译码设计具有计算速度快、占用资源少的特点,并且能应用到航天分包遥控通信中。
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, sim- ulation and verification are also given based on FPGA. The simulating resuhs 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 communi- cation.
