So here the microcells are required. Microcells cover almost 1Km radius so the areas where the macro cells are unable to provide services, microcells are used. Microcells are deployed relatively closer than macro cells so they experience intercell interference, which occurs when UE(user equipment) is at edge of a cell and receiving signals from two base stations simultaneously but with same carrier frequency, here problem arises for the user for the selection of base station, so DCS (Dynamic cell selection) is applied between the cells to reduce the interference between the cells.","PeriodicalId":6305,"journal":{"name":"2003 IEEE Topical Conference on Wireless Communication Technology","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87825254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mobile communication technology is now in acritical period in the evolution of network technology. As such, LTE (Long Term Evolution) comes to light. LTE serves as a unified standardfor the new generation of mobile communications, equipped with high spectral efficiency, high peak rate, high mobility, flat networkarchitecture 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 architectureand Network performance evaluation and so on. This paper mainly introduces the problems encountered in the optimization of LTEnetwork 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.","PeriodicalId":6305,"journal":{"name":"2003 IEEE Topical Conference on Wireless Communication Technology","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81642760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 antennauses the digital signal processing technology to generate the spatial directional beam so that the antenna main beam is aligned with thedirection 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 fullefficient use of the mobile subscriber signal, thus remove or suppress the interference signal purpose. Compared with other increasinglydeep and mature interference removal technology, the application of smart antenna technology in mobile communication is even more in theascendant and showing great potential. One of the key technologies of the third generation mobile communication standard TD-SCDMAsystem submitted by our country is the intelligent antenna technology. The paper introduces the history and development of the smartantenna in detail, and deeply analyzes the application of the smart antenna in TD-SCDMA.

How to ensure that thecommunication is effective, accurate and rapid in the harsh environment conditions in front of today's communications researchers is adifficult problem. As the mobile communication system must use wireless transmission technology in order to achieve the exchange ofinformation in the mobile, wireless transmission is vulnerable to a variety of other radio waves interference, a large number of interferencewill greatly affect the quality of network communications and system capacity. Anti-jamming technology with strong resistance, strongtechnical, difficult, practical and reliable high characteristics, in today's increasingly harsh electromagnetic environment, anti-jammingtechnology is particularly compelling. It can greatly improve the effectiveness and reliability of the communication system in thecommunication system. Today, anti-jamming technology has become the mainstream of radio communications technology, it is the mostclosely linked with the field of communications.

In MANET the node can move in any direction independently. The main challenge in building a MANET is equipping each device to continuously maintain the information needed and to properly route traffic. So, these networks may operate by themselves or may be connected to the larger  Internet . They may contain one or multiple and different transceivers between the nodes. Finally in a highly dynamic, autonomous topology . Vehicular Ad-hoc Networks (VANETs) are used cars and cars and roadside equipment.
