Popis: | In a standard Differential Chaos Shift Keying(DCSK), the reference signal and information bearing signal are sent in separate and equal time slots. In this paper, A new chaos based communications system is proposed by sending the reference signal and information bearing signal in one time slot utilizing the orthogonality between chaotic segment and its time flipped version. This doubles the data rate and enhance Bit Error Rate(BER) performance with respect to DCSK. The proposed system is evaluated using real time simulations in AWGN channel. Moreover, a time flipping unit is designed to synchronize each chaotic segment with its mirrored version. Results indicate that the proposed scheme has an average gain of 4 dB in comparison to the standard DCSK at moderate Eb/No values. |
