The simulation program by the Monte Carlo method of pulse reactions of bistatic atmospheric aerosol-gas channels of optical-electronic communication systems (OECS) is created on the basis of the modified double local estimation algorithm. It is used in a series of numerical experiments in order to evaluate statistically the transfer characteristics of these channels depending on the optical characteristics of an atmosphere plane-parallel model for wavelengths λ = 0.3, 0.5, and 0.9 μm at a meteorological visibility range SM = 10 and 50 km. The results are obtained for a set of basic distances between the light source and the light receiver up to 50 km and for the angular orientations of the optical axes of a laser radiation beam and of the receiving system in a wide range of their values. The dependences of the pulse reactions maximum values over-the-horizon channels of the OECS on the variations of these parameters are established.

Machine learning (ML) has been broadly connected to the upper layers of communication systems for different purposes, for example, arrangement of cognitive radio and communication network. Nevertheless, its application to the physical layer is hindered by complex channel conditions and constrained learning capacity of regular ML algorithms. Deep learning (DL) has been as of late connected for some fields, for example, computer vision and normal dialect preparing, given its expressive limit and advantageous enhancement ability. This paper describes about a novel use of DL for the physical layer. By deciphering a communication system as an auto encoder, we build up an essential better approach to consider communication system outline as a conclusion to-end reproduction undertaking that tries to together enhance transmitter and receiver in a solitary procedure. This DL based technique demonstrates promising execution change than traditional communication system.

Contemporary Technology

Pseudorandom number generators are used in many areas of contemporary technology such as modern communication systems and engineering applications. In recent years a new approach to secure transmission of information based on the application of the theory of chaotic dynamical systems has been developed. In this paper we present a method of generating pseudorandom numbers applying discrete chaotic dynamical systems. The idea of construction of chaotic pseudorandom number generators (CPRNG) intrinsically exploits the property of extreme sensitivity of trajectories to small changes of initial conditions, since the generated bits are associated with trajectories in an appropriate way. To ensure good statistical properties of the CPRBG (which determine its quality) we assume that the dynamical systems used are also ergodic or preferably mixing. Finally, since chaotic systems often appear in realistic physical situations, we suggest a physical model of CPRNG.

Efforts to solve environmental pollution in densely populated communities in urban areas are not only the responsibility of the government. Communities as part of social system also have an important role to control the environmental impacts of pollution. One way that community members must do in reducing environmental damage is familiarize environmentally friendly behavior. This research focuses on the analysis of environmentally friendly behavior of Pulo Geulis community members in Bogor City. Pulo Geulis is a Delta in the middle of the Ciliwung River which more or less contributes to whether or not the Ciliwung River is polluted in Bogor City. The communication process is an important factor in changing individual behavior. This study aimed to analyze the structure of community communication networks in developing environmentally friendly behavior. Primary data was obtained through a survey of 100 respondents and in-depth interviews with several informants. Data were analyzed using sociometric methods. The results of sociometric analysis showed that the structure of the community communication network in building community-friendly behavior is a radial personal network. This structure illustrated that community information centers are located in certain individuals such as head of RW, head of RT, or Posyandu cadres. The radial personal network in this study also described the formation of clique, star, bridge, and isolates in the community communication network at Pulo Geulis.

In recent years, wireless sensor network technology has continued to develop, and it has become one of the research hotspots in the information field. People have higher and higher requirements for the communication rate and network coverage of the communication network, which also makes the problems of limited wireless mobile communication network coverage and insufficient wireless resource utilization efficiency become increasingly prominent. This article is aimed at studying a support vector regression method for long-term prediction in the context of wireless network communication and applying the method to regional economy. This article uses the contrast experiment method and the space occupancy rate algorithm, combined with the vector regression algorithm of machine learning. Research on the laws of machine learning under the premise of less sample data solves the problem of the lack of a unified framework that can be referred to in machine learning with limited samples. The experimental results show that the distance between AP1 and AP2 is 0.4 m, and the distance between AP2 and Client2 is 0.6 m. When BPSK is used for OFDM modulation, 2500 MHz is used as the USRP center frequency, and 0.5 MHz is used as the USRP bandwidth; AP1 can send data packets. The length is 100 bytes, the number of sent data packets is 100, the gain of Client2 is 0-38, the receiving gain of AP2 is 0, and the receiving gain of AP1 is 19. The support vector regression method based on wireless network communication for regional economic mid- and long-term predictions was completed well.

Nowadays, the network traffic has increased exponentially due to amount of information and number of users which are connected to Heterogeneous Networks (HetNets) in this case we focus on LTE-WiFi technologies. This is an important issue that need to solve for an efficient network communication process end to end. The aim of this article is to present the-state-of-theart about performance models for LTE-WiFi HetNets and a classification of key performance metrics which help to analyze HetNets behaviour. The article concludes with a methodology that will be applied later for this research problem, as well as opened research questions. We believe, that apply our methodology using accurate and suitable models in HetNets the transmission process will have a fairness traffic when both networks coexist.
