Realization of orthogonal codes based on dyadic additive group by software

正交编码是码分多址通信的关键技术之一,为了达到全球通信的目的需要多种多样的编码方法。对于通信设备来说,不同CDMA 编码体制的转换与沟通是需要解决的重要问题。正交码的软件实现给出了解决问题的途径,提出了基于并元加性群的正交码编码方法,并以二进制为例给出了产生正交码的部分 C 语言程序,使通信系统应用更加灵活,为软件无线电的实现开辟了道路。

Orthogonal code is one of the key technologies of CDMA communication.In order to achieve the goal of global communication,we need a variety of code ways.To communication facilities,the transformation and communication in different CDMA code systems is an important problem and needs to be resolved.Realization of orthogonal codes by software offers a method to settle the problem.Orthogonal codes method based on dyadic additive group is proposed.Moreover,take binary system for example,a C language program which produces orthogonal codes is put forward.It will make communication system more flexible and open the road for the realization of software radio.
