摘要: 提出了亏格g=1的复数旋转码GICR的概念,利用多层环面完全嵌套的方法给出了 GICR码的直观模型。GICR码是复数旋转码从二维空间到三维空间的推广。利用弱区组设计的概 念讨论了该码的极小距离与纠错能力,同时研究了GICR码的对偶码,给出了GICR码及其对偶码 的主要参数。Abstract: The concept of complex-rotary codes of genusg=1 is proposed in this paper. By means of the complete embedding of multi-layer ring surfaces, a visual model of GICR codes is given. The codes are the extension of complex-rotary codes from 2- dimensional space to 3-dimensional space. By using the conception of the weak block design, the minimum distance and error-correcting capability of the codes are discussed. Meanwhile, the dual codes of GICR codes are studied, and the main parameters of GICR codes and their dual codes are also presented.
