Td-scdma Indoor Coverage Means And Transmission Amplification Equipment

This paper mainly analyzes the indoor coverage of TD-SCDMA.TD-SCDMA is the first complete mobile communication standardization of China. There are already some operators kick off the construction of the network, but some details are also needed to be discussed.Moreover,the technology of smart antenna in TD-SCDMA can not be used in the indoor scenario,so we should consider the indoor coverage separately.In this paper,we bring forward the design pattern for TD-SCDMA to improve the indoor coverage. First,we describe the architecture of the indoor coverage system as well as the planning,the network distribution way and design index.Then we analyze the signal source and application scenario of the indoor coverage system and also discuss the voice load budget,way of construction for different types of coverage areas.Based on it,we give the detailed analysis of the performance for the indoor coverage system of TD-SCDMA. For indoor coverage system of TD-SCDMA,we consider the balance of the downlink and uplink,uplink interference,synchronization,the protection of the electromagnetic radiation and leak of the signal.Also,the frequency planning,code planning and system parameters configuration for TD-SCDMA are included.Finally,the performance of the amplifier for the indoor coverage system of TD-SCDMA is investigated including performance analysis of different topologicals to deploy the amplifiers.
