Abstract :
In this article the capacity expression is derived for M-ary Differential Chaos Shift Keying (M-DCSK) modulation over additive white Gaussian noise (AWGN) channel. Then the capacity bound curves of M-DCSK are provided by Monte Carlo method. Theoretical analysis and simulation results show that the high dimension DCSK modulation has more obvious capacity advantage than the conventional modulations. So they are appropriate for the power-limited communication systems.
