| As the development of wireless telecommunication technology and the growth of the demanding of high-speed data service, based on 3G system,3GPP proposed some enhanced wireless technologies in release 5, the gather of these technologies is called HSDPA. According to the survey, most of the data services are used in indoor environments, in order to extend the coverage of indoor signal, Home Node B is proposed by 3GPP in 2007.In this paper the interference of HSDPA and Home Node B were studied by a system level simulation. First of all the key technologies of HSDPA are studied, including AMC, HARQ, fast scheduling algorithm and multi-spectrum. In this paper the structure of Home Node B and some typical application scenario are intruduced, furthermore the interference scenario in 3GPP are analyzed. finally with the help of system level simulation, the interference between TD-HSDPA Home Node B are studied from several aspects including the schedule algorithm, the density of Home Node Bs, the frequencies and the output power of Home Node B. The results of the study will be given by CIR, user satisfied rate and throughput. |
