Use of wireless telecommunication system with code channels division based on modified pseudorandom gold sequences for the information transmission from surveillance cameras

The present study aims to implement a discrete event simulation (DES)-based model. This model is called coding of bits for entities by means of discrete events (CBEDE) and aims to improve the transmission of content in wireless telecommunication systems. This is done by applying advanced modulation format DQPSK in a simulation environment, the Simulink of the MATLAB software, through a pre-coding process of bits applying discrete events in the signal before of the modulation process, occurring in the discrete domain with the implementation of discrete entities in the process of bit generation applied at a low level of abstraction in a wireless telecommunication system. The results show improvements of 89.08% in memory utilization, related to information compression, in the context of the research. Therefore, the presented results of the proposed methodology show an enormous potential for the non-orthogonal multiple access (NOMA) contexts, credited as the future 5G, and can compensate for the additional complexity brought by the techniques to the telecommunications channel.

The Media

IP-PBX based communication has become a human need in the era of technology. Some researchers design a wireless telecommunication system based on IP PBX using Raspberry Pi. The previous researches have small network coverage and problematic on the ability of the system to support multiple concurrent connections. Based on these problems, these research aims are to expand the coverage area and increase the number of concurrent calls. This study used Asterisk FreePBX for the media configuration of the servers. The clients: laptops and smartphone devices used Linkin and Bria softphone. The testing was conducted in terms of voice and video services in the form of signal strength, CPU performance of servers, and network performance parameters such as delay, jitter, and packet loss. The results obtained that the CPU performance of the servers for seven calls simultaneously is around 16.9% compared with previous research, at an average of 45%. Based on ETSI standards, the measurement of network performance parameters when communicating between clients outperform than previous research. The clients can communicate well up to 390 meters.

The 1960S

With the rapid development of science and technology, people to some degree have acquired enormous achievements in the field of robot, especially the intelligent robots.To make robots a system so as to coordinate their movements, telecommunication is a fundamental factor. And wireless telecommunication is definitely the most ideal way to connect robot with robot or robot with computers.Research on remote robot technology can date back to the 1960s. As mankind’s knowledge of nature as well as application of robots are on the rise, some inevitably abominable environments are brought about, such as volcano exploration, deep ocean discovery, space exploration and militant monitoring. However, all these jobs will cause damage to the operating personnel more or less and sometimes even death.Therefore, the ways of controlling robots have developed from traditional live controlling to wireless remote controlling.
