摘要
In this brief, we propose a multilevel version of the differential chaos shift keying (DCSK) telecommunication system. The scheme, that we call quadrature chaos shift keying (QCSK), is based upon the generation of an orthogonal basis of chaotic functions. QCSK is characterized by an increased data rate with respect to DCSK, with the same bandwidth occupation. The price for the performance enhancement is the increased complexity of both the transmitter and the receiver.
