Simulation and Analysis of Chinese Digital Audio Broadcast System on Base Band

In this paper, a simulation model is put forward using Matlab and Simulink based on "Specification of 30MHz-3000MHz terrestrial digital audio broadcasting system" issued by China. All transmission modes in the specification have been simulated, and the results of simulation were analyzed. We concerned more on the Doppler Shift than the SNR in simulation. Results of simulation prove that effect of the Doppler Shift is in main position in mobile reception while effect of the SNR is in main position in fixed or low-speed movement reception.
