Abstract
Abstract—A new Multi-Carrier Differential Chaos Shift Keying
(MC-DCSK) modulation is presented in this paper. The
system endeavors to provide a good trade-off between robustness,
energy efficiency and high data rate, while still being simple
compared to conventional multi-carrier spread spectrum systems.
This system can be seen as a parallel extension of the DCSK
modulation where one chaotic reference sequence is transmitted
over a predefined subcarrier frequency. Multiple modulated data
streams are transmitted over the remaining subcarriers. This
transmitter structure increases the spectral efficiency of the
conventional DCSK system and uses less energy. The receiver
design makes this system easy to implement where no radio
frequency (RF) delay circuit is needed to demodulate received
data. Various system design parameters are discussed throughout
the paper, including the number of subcarriers, the spreading
factor, and the transmitted energy. Once the design is explained,
the bit error rate performance of the MC-DCSK system is
computed and compared to the conventional DCSK system under
multipath Rayleigh fading and an additive white Gaussian noise
(AWGN) channels. Simulation results confirm the advantages of
this new hybrid design.
