The Realization Technology Research Of TD-SCDMA Based On Software Radio

SDR (Software defined radio) is a simple and general hardware platform, through the heavy configuration, can upgrade the software to realize all kinds of radio function. Software radio for wireless communication system can have good flexibility and universality, make the system upgrades and Internet has become very convenient. TD-SCDMA is China has independent intellectual property rights of the third generation mobile communication standard. China is formally submitted to ITU one of three in3G standard.This article is based on the TD-SCDMA SDR is studied. It to the TD-SCDMA physical channel and SDR components are discussed, in this based on the proposed one kind based on the wideband band-pass sampling SDR TD-SCDMA terminal receiver hardware module design. Module hardware design includes:A/D converter. DDC and DSP. are discussed in detail in the A/D converter and a DDC device design and application:software design includes:DSP baseband signal processing and parameter design of DDC filters. Through this research, indicates that in the third generation mobile communication software radio application is feasible.
