Mobile Communication Industry

There are different communication standards in present mobile communication industry. Each of this standards has its own feature, architecture, and channel assignment strategies. Each mobile operator uses one of any standard and their aim is to support as much user as possible to communicate with tolerable interference. For that reason they use different cluster size and frequency planning to cover entire geographical area. To reuse the given bandwidth within the entire geographical area some cells uses same sets of frequency and interference arise when the distance between these cells is small. Also when distance is large then capacity is going low. In this thesis our work is to investigation the co channel interference among different cluster size assuming a limited sub urban geographical area in a cellular GSM network. Also we calculate the number of users using each of this cluster size and finally design a cellular system in this geographical area using best results (minimum interference and maximum capacity).

Shift Keying

Phase shift keying modulation approaches are widely used in the communication industry. Differential phase shift keying (DPSK) and Offset Quadrature phase shift keying (OQPSK) schemes are chosen to be investigated is multi environment channels, where both systems are designed using MATLAB Simulink and tested. Cross talk and unity of signals generated from DPSK and OQPSK are examined using Cross-correlation and auto-correlation, respectively. In this research a proposed system included improvement in bit error rate (BER) of both systems in  the additive white Gaussian Noise (AWGN) channel, by using the convolutional and block codes, by increasing the ratio of energy in the specular component to the energy in the diffuse component (k) and  the diversity order BER in the fading channels will be improved in both systems.

New Media Technologies

Many new media technologies have emerged in modern society. The application of new media technologies has impacted traditional TV news media, which not only faces great challenges, but also brings some lessons for the development of TV news media. New media technology relies on powerful information processing technology and data storage technology to develop and grow continuously. Compared with traditional news, new media technology has more powerful information storage capacity and dissemination capacity. Firstly, this paper briefly introduces the concept of new media technology, summarizes the typical characteristics of new media technology, and analyzes the existing problems in the application of new media technology in the news communication industry based on the necessity of applying new media technology. Finally, some Suggestions are put forward based on this, hoping to provide some reference for the development of news communication industry.

Late Growth

We selected the constant price GDP and telecom business volume as the national economy and communications industry development metrics. First, we analyzed China's communication industry development in China since 1978 according to the industry life cycle theory. Then we used the time series model by detrending to make the two sequences stationary and took Granger causality test. The results show that China's telecommunications industry is in the late growth stage. There is a unidirectional causality from GDP to the direction of the telecom business volume.
