摘　　要：在卫星通信中,受到自由空间损耗、多径、噪声、多普勒频移等影响,数据传输容易产生误码,为了确保传输的可靠性,需要设计高效的纠错方法来检测误码的产生,以便后续采取相应的处理措施。该文基于CRC编码的原理,设计出一种基于Labview的高效CRC发生器,将其应用在卫星指令设计中,并对其性能进行了分析。文中提出的CRC编码方法较传统方法更简洁高效,可以极大地提升运算处理的速度。In satellite communication,affected by free space loss,multi-diameter,noise,Doppler frequency shift,data transmission is easy to produce errors,in order to ensure reliability transmission,it is necessary to design efficient error correction methods to detect the generation of errors,in order to follow up the corresponding processing measures. Based on the principle of CRC coding,this paper designs an efficient CRC generator based on Labview,applies it to satellite instruction design,and analyzes its performance. In this paper,it is proposed that the CRC generation method is simple and efficient compared with the traditional method,which can greatly improve the speed of computational processing.
