Abstract
In this paper, a new noncoherent Differential Chaos Shift Keying is proposed and named Extended -Differential Chaos Shift Keying (E-DCSK). Each pair of bits is modulated using two different versions of the same chaotic reference signal; the first information bit is modulated with the chaotic reference signal block while the next information bit is modulated after reversing samples' order of the same reference block. This saves the transmitted signal energy in addition to reduce the repeated components in the signal spectrum. Bit-error performance in additive-white-Gaussian-noise of the proposed system is analyzed and compared with the other chaos based communication systems. Results show that the bit-error rate performanceof the E-DCSK is often better than other schemes when spreading factorisrelatively low. Also, clear matching between theoretical analysis and simulation result is observed.
