根据相移键控原理,提出了一种不可逆DWT域二相相位键控数字图像水印算法。 2. Two methods of tap number selection of Phase Shift Keying(PSK) modulation signal equalizer were proposed,including the maximum residual Inter Symbol Interference(ISI) criterion and signal decision error probability criterion. ...
The output of the lookup table becomes a timing weighing figure, which is multiplied with an output of the loop phase shifter and then input into the timing adjust block for adjusting timing of a PM signal. Phase error may be corrected with minor additional components....
where the carrier frequency fc is an integer multiple of the symbol rate 1/Ts. Using (7.1a), the following shows that the energy of each signal is the same as the average energy per symbol Es: (7.12b)Ei=∫0Tbsi2tdt=Es,i=1,2,3,4 After using a well-known trigonometric identity to...

CONSTITUTION:A symbol 10 is a glass substrate and a light shielding film 11 is patterned on the glass substrate to form transparent parts 12. Phase shift films 13 are formed in the specific parts on the transparent parts 12. The thickness of the phase shift films 13 on the one transparent...
the filter is kept at a fixed frequency and all of the light in the cavity is shifted in frequency on eachround trip. The frequency shift can be implemented by either an acoustooptic frequency shifter[17]or by a phase modulator[18]. This laser is an interesting hybrid between active and ...
However, the bandwidth and stability of the electric phase shifter may affect the performance of the system. In this paper, a scheme for generating fundamental/doubled frequency phase-coded microwave signals based on polarization multiplexed technology is proposed. The +1st-order CS-SSB of the LO...
With an experimental study, we observe that the π-phase-shifting efficiency of the topological phase shifter is 1.57 times that of a conventional waveguide-based phase shifter. The high phase-shifting efficiency of the topological waveguide can benefit the thermo-optic switch through a reduced ...
