The Simulation And Properties Research In DMR (Digital Mobile Radio) High-level Transfer Mode

With the development of Mobile Communication, Private Mobile Radio becomes more and more important for its advantages. In 2004, a new digital wireless communication systems DMR(Digital Mobile Radio)agreements raised by ETSI, the advantage of which are low cost, simple technology and supports from analog to digital transition. So the terminals based on DMR agreement attract extensive concern. DMR digital terminals development both domestically and abroad are still in its infancy.A simply description about the content of DMR and the calling process is made .Mainly do the research in transfer mode. Especially, do researches on the high-level of the base station and its work flow. Introduce how the base station harmony the Both-Slot .With the help of BCB platform, design software model of transfer mode communication protocol and establish interface. Download the source code to digital base board, proving the feasibility of software module of transfer mode .It has verity the correctness and feasibility of procedure. Finally, simulate the call rejection rate, and make a compare with theory value.
