短信寻呼台所发射的信号有的采用二元BCH码进行编译码，这种码具有良好的代数结构和极强的纠错能力。这里介绍一种短信信号发射所采用的译码器的快速搜根算法，并设计了一种高效可行的搜根器，其电路设计行之有效，搜根速度快，在通信系统中可以提高译码器的译码速度。随着手机的迅速普及，提高短信息的发送质量，可以适应电信市场经济的快速发展，提升电信运营商的竞争能力，因而具有一定经济价值和应用前景。%The signals of SMS paging station transmitted apply some binary BCH code to encode and decode. this code has good algebraic structure and strong error correction capability. Here introduces a quick searching root algorithm about the BCH(31,21,5) decoder of SMS signal transmission and design a feasible and efifcient searching root device. circuit design is effective, it can search root quickly. It can improve decoding speed in communication system. With the rapid popularization of mobile phones, improving quality of the sending messages can adapt to the rapid economic development of the telecommunications market and enhance the competitiveness of the telecom operators, so it has a certain economic value and application prospect.
