i can't juste delayed the signal, i muste obtain the same sequence with a 90° phase shift.
I try to get the Hilbert transformed for a chaotic signal in order to have two signals completely orthogonal -> Chotic signal and Hilbert Transform of chaotic signal
in MATLAB all goes well, I...
I just tried it but the signal obtained are not orthogonal to the starting signal, i need it for QCSK modulation, i tried also analytic signal blocks and i take only the imaginary part of the result but i am not satisfied. Hilbert tranform must return the same signal with 90° of dephasage. with...
when i tried to do simulation in simulink of CDSK modulation i obtain the following signals
2. chaotic signal
3. dataxchaotic signal delayed
4. addition of 2 and 3
5. Delayed version of 4
6. product of 4 and 5
7. output of my correlator at reception
I am a PhD student, I work on digital modulations (CSK, DCSK, CDSK, QPSK, BPSK, QCSK ...), I work mostly on digital modulations based on chaos. However I am in blocking state for more than ten days in my work, I can not get a good BER in my simulation of CDSK modulation. for information, i work...
