摘要:
为克服传输线带宽受限的困难,利用Chen-Möbius变换生成的函数族的斜正交性设计一种高速保密的通信系统,并通过DSP Builder仿真平台验证了通信系统的正确性.采用高速A/D转换将各种信号都转换成数字信号,然后将串行的数字信号转换成N位一组的并行信号,每位信号(1或0)用一个特殊变换函数族的逆变换波形进行编码.输出时,这N位(或N个)编码波形是直接叠加在一起,从一条传输线上输出的,而在接收端,这些输出的信号被同时输入N个并行的信号判别端.每个判别端生成一个特殊变换函数的正函数信号与送入的N个编码波形的叠加进行正交积分运算,判别出每一位的数字信号.
Abstract:
To overcome the difficulties of limited bandwidth transmission in line, a high-speed confidentiality communication system is designed using the oblique-orthogonality of function sets evaluated by Chen-Möbius transform, and the correctness of the communication system is verified through DSP Builder simulation platform. By using the high-speed A/D converter, a variety of the signals are converted to digital signals, then, the serial digital signals are converted into a set of N-bit parallel signals, each signal(1 or 0)be coded by the inverse transform of a special transformation function sets evaluated by Chen-Möbius transform. When they been transmitted through the line, this N-bit(or N)encoded waveform is directly mixed together. At the receiver, these output signals are simultaneously put into N parallel discriminations of signal. When the N-bit(or N)encoded waveform was calculated by means of the orthogonality integral with each function set which was generated by the discriminations of signal, we can identify each of the digital signal.
