Design and Simulation of High-Confidentiality Communication System Based on Chen-M(o)bius Oblique Orthogonality
摘要
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-Mobius 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 e-valuated by Chen-Mobius 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.关键词
