The Study On The Key Technologies Of Receiver In SDR-Based GSM System

Software defined radio is a new kind of concept and architecture ofwireless communication emerged in the past few years which hasreceived much attention at home and abroad. It is a collection ofhardware and software technologies that enable reconfigurable systemarchitectures for wireless communication systems. It introduces thegenerality and flexibility into the traditional wireless communicationsystem and will make the interoperation among different communicationstandards and the system upgrade much easier. Because of all theseadvantages, it becomes the third breakthrough in the wirelesscommunication and the key technology of the third generationcommunication.After having studied the basic framework and key technology ofSDR, this paper has done further research on the multi-sampling rate inSDR and has derived the specific algorithms for our SDR platform.Besides; more attention has been paid to the key technology in GSMsub-system receiver.
