Data transmission method and apparatus and data receiving method and apparatus for multiple access in chaotic communication system

摘要

A data transmission method and apparatus and a data receiving method and apparatus provide for multiple access in a chaotic communication system. The data transmission method includes arranging a template chaotic signal at a predetermined position of a data frame to be transmitted, the predetermined position being allocated to a user, modulating a data source signal using the template chaotic signal and arranging the modulated data source signal in the data frame, and transmitting the data frame.
