Based On Software Radio Multi-channel Digital Receiver

The software radio technology is a key to the development of future communication. Intermediate Frequency(abbr. IF) digital processor module is an important part of the digital receiver which uses the software radio technology. AD6652 , which has high accuracy, quick converting acceleration and so on, is the new Analog/Digital Converter(abbr. ADC) devices of Analog Devices and the best selection of AD converter in the present IF digital processor.In this thesis, the author summarizes the Software Defined Radio(abbr.SDR) technology, carries out a multi-channel digital receiver module based on SDR and the new ADC device AD6652 and introduces the module's hardware and software design in detail.The main results are as follows:1. summarization of SDR2. hardware design of a multi-channel digital receiver based on SDR and the new ADC device AD6652 including system, A/D, DSP and power etc.3. software design of a multi-channel digital receiver based on SDR and the new ADC device AD6652 including signal demodulation, initialization and SDR demodulation arithmetic etc.4. module's PCB and its test.
