本文对复数旋转码特性作了进一步的分析研究,通过扩展复转码及监督元压缩,提高了码效。同时,分析了复转码的不同纠错能力层次的设计,超限译码,并从组合设计的基础上,推广了复转码,提出了构造一类大数逻辑可译码的方法,最后,用微机实现了集调制、加密、编码于一体的多功能modem。
In this paper, the properties of complex rotation codes are further analyzed and studied. The code efficiency is improved by expanding the complex transcoding and supercomponent compression. At the same time, the paper analyzes the design and the transfinite decoding of different error correction ability levels of complex transcoding. Based on the combined design, the complex transcoding is generalized. A method of constructing a class of large transcoding logic is proposed. Finally, , Using a computer to achieve a set of modulation, encryption, encoding in one multi-mode modem.
