提出了差错控制编码方法来解决LED大屏幕远程通信系统显示信息高速率串行传输数据可靠性降低的问题。考虑到显示信息发送端和接收端的硬件基础及实现要求不同,提出在发送端采用并行算法结构,并构造了生成矩阵进行编码运算来提高算法的实时性;在接收端采用双时钟串行循环译码电路结构,在伴随式计算后采用高速时钟进行纠错,使得码字较长的编码仍旧能够获得较低的硬件开销并具备较好的实时译码能力。实验及理论分析表明,提出的方案能够实现高效率的编解码运算,编码效率达到98.2%。该方案也有效地降低了误码率,实际应用中误码率至少降低了1个数量级。使用提出的方案实现了显示信息的高速率、高效率串行传输。
The error control coding method is put forward to solve the problem that the reliability of LED high-speed serial transmission data of LED large-screen telecommunication system display information is reduced. Considering the different hardware and implementation requirements of the sender and the receiver, we propose to use the parallel algorithm structure at the sending end and construct the generator matrix to improve the real-time performance of the algorithm. At the receiving end, a dual-clock serial loop Code circuit structure, using the high-speed clock to carry out the error correction after the companion calculation, so that the code longer code still can get lower hardware overhead and have better real-time decoding ability. Experiments and theoretical analysis show that the proposed scheme can achieve high efficiency codec operation, and the coding efficiency reaches 98.2%. The scheme also effectively reduces the bit error rate, the actual application of bit error rate reduced by at least an order of magnitude. The proposed scheme realizes high-speed and high-efficiency serial transmission of information.
