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。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
