1 Digital modulation 8 PSK presentation of LabVIEW source code.

2 An all digital preambleless burst mode PSK demodulator is also proposed and studied.

3 Digital mod technology in the digital communication occupies a very important position, commonly used digital modulation are: frequency shift keying (FSK) and phase-shift keying (PSK), and so on.

4 The signal types include SSB, DSB, PSK, AM, ASK, FM, FSK etc.

5 Several demodulation schemes for split phase coded PSK signals are described in this paper.

6 PSK spread spectrum system that uses the digital correlator is explored and designed.

7 According to the characteristics of 2 PSK signal, a 2 PSK demodulator design scheme based on CPLD is suggested.

8 Generally speaking, PSK system performance than switch Keying FSK system well, but must use synchronous detector.

9 A scheme to achieve ultrahigh speed all-optical format conversion from on-off keying (OOK) to phase-shift keying (PSK) by using the linear filtering in the silicon ring resonators is proposed.

10 Basing on the properties of binary digital PSK and exclusive-OR gate, this paper gives a quite simple exclusive-OR gate for binary PSK.

11 Because MSK phase is continuous, the rolloff velocity of the MSK spectrum to the PSK was improved greatly.

12 The binary data bit of OFDM is modulated on the corresponding subcarrier by PSK or QAM.

13 However, after the inter-slot silent period, the ramp output signal during the 8- PSK mode does not track the ramp input signal.

14 In this paper, we propose a new method for recovering binary code sequences from base-band, FSK or PSK signals transmitted through Gaussian noise channel.

15 Studies the function of wavelet transform (WT) that can effectively distill the transient characteristics of digital signals to estimate the symbol rate of PSK signals.
