Based on the idea of the Schmidt orthogonalization and the orthogonal chaotic carriers being generated,a chaos-based quadrature modulation communication system is proposed and realized. The results by computer simulation indicate that under the environment of channel noise and multipath interference,for single-user and multiuser communications,the proposed system is superior to the CSK and QCSK systems. In addition,the system is simple and easy to implement.
