Software-defined Radio Receiver Design and Development for China Digital Radio (cdr)

China digital audio broadcasting in FM band (commonly referred to as CDR) is a newly released digital audio broadcasting standard (GY/T 268-2013) which operates in the FM-band (87MHz to 108MHz) in China. This report introduces this standard in English for the first time which is based on an official version written in Chinese, including multiplexing, frame structure, channel coding and modulation schemes, etc. In the report, a CDR receiver simulation chain is designed and tested. To be specific, several problems of the CDR receiver are investigated and analyzed including local oscillator offset, Doppler shift and time-variation. Solutions for every problem are explored and implemented in Matlab selectively. Together with the multipath channel modeling and the defined transmitter model implementation in Matlab, the complete FM-band digital audio broadcasting chain is simulated and tested. The proposed solution of the CDR receiver indicates the applicability of the FM-band digital audio broadcasting standard. It is a preliminary research on CDR standard and may be improved in the future. care and encouragement in my life and study; I would like to thank Dr.Ir Rob Kooij of TNO for the instructions during my internship which gave me the confidence and platform to do my thesis project in NXP Semiconductor; I would like to thank Audrey Cuenin of EPFL for accompanying and supporting me during this project; I would like to thank my parents for their supporting me on my study, caring about my life and selfless love.
