In this paper we present simulation results comparing the performance of CMA and backpropagation to compensate the chromatic dispersion in a NGPON with QPSK phase modulation
and coherent detection.
Therefore, while choosing the frequencies of the tones for pump phase modulation
it is required to find a compromise between the efficiency of SBS mitigation and idler spectral broadening, or to implement one of the techniques designed to reduce broadening of the idler spectrum , .

The NRL ATS software can be customized to control the SLM to produce the phase modulations
and simulated turbulence levels through a Graphical User Interface (GUI).
s6) finally, the calculus of the signal phase modulation
law 0(t), using the following well-known equation, namely:
The first improvement is to compensate the range-invariant and residual range-variant phase errors together in the range-compressed time-domain before RCMC, which is used to eliminate the phase modulation
errors of the RCM by the greatest extent.
Analog synthesis, frequency, phase modulation
, and specifics on four popular music synthesizers and their unique techniques makes for a solid, powerful guide hard perfect for any electronic musician's reference library.
A new electronics and communication interface provides faster data acquisition, larger phase modulation
amplitude and greater overall step-scan performance, enhancing capabilities for studying chemical kinetics and dynamic modulation processes.
The magnitudes of the in-phase and quadrature output signals of the input Lange splitter, adjusted with the balanced attenuators, are summed with a simple output Wilkinson combiner, which allows magnitude and phase modulation
of the RF carrier.
For communications signals, this includes AM, FM, phase modulation
, multichannel FM/FM signals, single sideband (upper or lower sideband), and various digital modulations.
The concept involves phase modulation
of the interrogating microwave field, rather than the traditional frequency modulation used in most atomic clocks.
