The value of residual phase noise, after compensation, is one the key limitations performance improvement for continuous-variable quantum distribution using a local oscillator (LLO CV-QKD) system, since it major excess noise. However, due to nonideality realistic devices implemented in practice, example, imperfect lasers, detectors, and unbalanced interferometers, noise current system still rel...

this paper considers the spatial planning system in russian federation. study of spatial planning system of russia specifies three different stages from each other. the first phase consists of the sixteenth century until the early twentieth century. in this period, base of the spatial planning was formed and gradually developed during approximately 400 years. the next phase is devoted to soviet...

We apply an AM-FM surface albedo model to analyze the projection of surface patterns viewed through a binocular camera system. This is used to support the use of modulation-based stereo matching where local image phase is used to compute stereo disparities. The local image phase is an advantageous feature for image matching, since the problem of computing disparities reduces to identifying loca...

election and electing publics authorities, statemen, parliament representative and local council,s members by people is un undeniable prerequisites of democracy. a state claiming democracy but lacking institutions as electoral systems and referendum could not be found. nevertheless electoral procedures are not identical everywhere. in some countries the nominee has to obtain the landslide (simp...

This paper describes the influence of local oscillator phase noise on single and multi-carrier modulations schemes. The oscillator has the main role on modulation and demodulation process of the radio frequency channels. The synchronization of the entire system depends on the accuracy of this circuit. This work is based on the simulation of these two scenarios under influence of a non-ideal osc...
