Fiber nonlinearities such as self phase modulation (SPM) and cross phase modulation (XPM) have drawn significant consideration [2].

Consequently, having as starting point a signal with rectangular envelope and phase modulation law given by (13), the absolute of the estimated spectral density function assigned to this signal [S.

The output of two efficient constant envelope RFPAs is power-combined so that amplitude modulation of the combined output can be affected by the introduction of differential phase modulation on the two input signals.

Both frequency modulation and phase modulation fall under the general category of angle modulation.

This stimulus feature, the sign of frequency difference, is concealed in the temporal pattern of amplitude and phase modulation in the sensory stimulus.

Electronic phase modulation of this kind will work well with fairly long-term processes, but electronic carrier waves have fairly low frequencies.

In addition to streamlining frequency usage through modulation methods such as polarization wave multiplexing and phase modulation, the technology enables significant improvements in reception sensitivity.

In this experiment the MZM is used for the phase modulation, the pseudo random bit sequence of 2 Gbps is applied to the 16-QAM modulation and the phase modulated signal output will given to the amplitude and phase pre-coding circuit.

The paper [16] uses conventional I-Q MSK modulator while phase modulation based on MSK modulator is presented in [15].

His topics include generations of solitons in optical fiber ring resonators, multi-bound solitons under carrier phase modulation, bound-soliton bispectra and nonlinear photonic signal processing, and multi-rate multiplication soliton fiber ring and nonlinear loop laser.

In addition to streamlining frequency usage through modulation methods such as polarization division multiplexing and phase modulation, the technology enables significant improvements in receiver sensitivity.
