二次扩展复数旋转码及其对偶码
On Secondly Extended Complex-Rotary Codes and Their Dual Codes
-
摘要: 扩展复数旋转码的基础上,提出了二次扩展复数旋转码及其对偶码的概念。就它们的特性作了初步的讨论,并给出了它们的生成矩阵的构造方式及主要参数。经过与扩展复数旋转码和其对偶码相比较,可以看出它们也是一类码率高、纠错能力强的差错控制码。Abstract: In this paper, the concepts of secondly extended complex-rotary codes and their dual codes are proposed on the basis of extended complex-rotary codes. Their characters are discussed preliminarily, and the method for their construction and their principle parameters are presented. By comparing the proposed codes with extended complex-rotary codes and their dual codes, it is shown that they are error controlling codes, the correction capacity of which is powerful and the code rate of which is high.
