平台光纤传输模块通过光纤完成惯导平台系统中的数据传输,其中一些关键数据如平台控制参数等直接影响到平台系统的状态,为了确保平台系统可以安全可靠地工作,必须对控制参数进行纠错,保证其准确性。由于RS 码具有强大的纠突发错误和随机错误的能力,被广泛应用于各种差错控制场合。文章设计了基于DSP 的RS(15,11)码的快速实现,完成对惯导平台系统中光纤传输的平台控制参数等关键数据的纠错。关键词:DSP ;RS 码;平台光纤传输;快速实现Abstract: In the inertial platform system, some data are transmitted by optical fiber under thecontrol of the optical fiber transmission module. Some key data like platform control parameters have a direct impact on the state of the platform. So the accuracy of the control parameters must be guaranteed by error-correcting to ensure the security of the platform system. The fundamental and coding -decoding algorithm of RS codes are presented, and fast implementation of RS(15,11) codes based on DSP are designed.Keywords: RS Codes; DSP; Optical Fiber Transmission; Fast Implementation
