carrier

n. in general, any person or business which transports property or people by any means of conveyance (truck, auto, taxi, bus, airplane, railroad, ship), almost always for a charge. The carrier is the transportation system and not the owner or operator of the system. There are two types of carriers: common carrier (in the regular business or a public utility of transportation) and a private carrier (a party not in the business, but agrees to make a delivery or carry a passenger in a specific instance). Regular transportation systems are regulated by states and by the Interstate Commerce Commission if they cross state lines. (See: common carrier, private carrier)

The paper is organized as follows: section 2 presents a description of QPSK phase modulation format and the CMA and backpropagation electronic compensation techniques.
The main goal of this article was to estimate the influence of FOPA pump phase modulation and of the mutual SOP mismatch between the signal and the pump at FOPA input on the efficiency and on the spectrum of the generated idler spectral components.
Although the prediction of the greater efficiency is usually correct, we cannot employ the phase modulation of the TE mode.
In addition, if the pulses exhibit phase modulation on pulse (PMOP), the phase transitions can be seen within the FMOP analysis window.
Phase modulation is also widely used in digital communications.
Phase modulation of the pump was used in order to mitigate the unwanted impact of Stimulated Brillouin Scattering (SBS) [8].
Errors such as phase modulation or in-channel spurious content can be detected by looking at displays such as the constellation, phase error versus time, or error vector spectrum.
The radar can also use other phase modulations such as quadrature-phase-shift keying (QPSK) or higher-level phase modulation (e.
Australian Patent 2005311947, entitled "Exploiting Multiuser Diversity through Phase Modulation Multiplexing," also recently granted, provides a method for combining multiple users onto limited spectrum.

1) Digital coherent transmission technology:An advanced optical transmission method that uses polarity multiplexing, phase modulation, and other modulation techniques to increase frequency utilization efficiency, and combines coherent reception and digital signal processing to greatly increase reception sensitivity.
As it can be seen from the obtained results, the first channel, where is used phase modulation, BER level is several orders lower ([10.
