Communication modernization is an important symbol of human societies as we enter into the information age. An important
problem encountered in modern communication is interference. With the development of communication, the establishment of various
communication networks, making the limited frequency of resources more crowded, intertwined to the serious. How to ensure that the
communication is effective, accurate and rapid in the harsh environment conditions in front of today's communications researchers is a
difficult problem. As the mobile communication system must use wireless transmission technology in order to achieve the exchange of
information in the mobile, wireless transmission is vulnerable to a variety of other radio waves interference, a large number of interference
will greatly affect the quality of network communications and system capacity. Anti-jamming technology with strong resistance, strong
technical, difficult, practical and reliable high characteristics, in today's increasingly harsh electromagnetic environment, anti-jamming
technology is particularly compelling. It can greatly improve the effectiveness and reliability of the communication system in the
communication system. Today, anti-jamming technology has become the mainstream of radio communications technology, it is the most
closely linked with the field of communications. This paper mainly discusses the interference problem of GSM system in mobile
communication anti-jamming technology, including the interference type in GSM, the anti-interference ability of GSM itself and how to
optimize the network to achieve the purpose of anti-jamming, so as to meet the requirements of users System capacity while maintaining
good call quality.

With the rapid development of global communications business, future personal communication wireless mobile communication
technology has aroused great concern. Way to eliminate the impact of co-channel interference (CCI), multiple access interference (MAI)
and multipath fading becomes a major factor in improving the performance of wireless mobile communication systems. The smart antenna
uses the digital signal processing technology to generate the spatial directional beam so that the antenna main beam is aligned with the
direction of arrival of the user signal. The side lobe or the zero point is aligned to the direction of the interfering signal to reach the full
efficient use of the mobile subscriber signal, thus remove or suppress the interference signal purpose. Compared with other increasingly
deep and mature interference removal technology, the application of smart antenna technology in mobile communication is even more in the
ascendant and showing great potential. One of the key technologies of the third generation mobile communication standard TD-SCDMA
system submitted by our country is the intelligent antenna technology. The paper introduces the history and development of the smart
antenna in detail, and deeply analyzes the application of the smart antenna in TD-SCDMA. The application of smart antenna has been

This article mainly describes the formation of various types of wireless LAN, as the current wireless LAN (Wireless LAN)
technology can be very convenient to wireless network equipment and mobile devices, people can access the network resources at anytime,
anywhere by communication Mobile, personalized and multimedia applications. In the continuous development of network technology,
wireless LAN is also changing our way of life, we can access to internet in amusement park, hotel, airport station and other areas. And in
school, teachers and students in the dormitory can have communication through the wireless LAN layout. Wireless LAN also has many
advantages and disadvantages, we need to understand the discovery of applications, this is the only way we can have a better life, learning,
and work.

The trend of mobile, broadband and IP is becoming more and more prominent. Mobile communication technology is now in a
critical period in the evolution of network technology. As such, LTE (Long Term Evolution) comes to light. LTE serves as a unified standard
for the new generation of mobile communications, equipped with high spectral efficiency, high peak rate, high mobility, flat network
architecture and other advantages. Huawei has played a very important role in the commercialization of LTE. As a sponsor of NGMN,
Huawei has been actively involved in the research of some key projects of NGMN, such as network self-optimization, system architecture
and Network performance evaluation and so on. This paper mainly introduces the problems encountered in the optimization of LTE
network coverage, the practical problems encountered by the LTE project team in Qingdao and the analysis and solutions to the problems.
At the same time, this paper discusses in detail on the LTE network optimization process.

In the 1990s, the development of program-controlled switches in our country has experienced the development process from the
scratch; especially the successful development of large-scale program-controlled switches has brought great vitality to our information
industry. This time, I mainly introduced to ZTE ZXJ10 program-controlled switchboard to design distributed modularization in programcontrolled
switch. ZXJ10 digital program-controlled switching system is distributed between modules, module classification control,
centralized management of the open architecture, based on general computer platform, LAN technology as the support, client/server mode
to control the basic form of structure, in order to make the system has flexible networking ability, strong call processing capability, high
reliability, good compatibility and expansibility.
