In this paper, we report DRM receiver synchronization methods at the acquisition stage. Synchronization process consists of robustness mode detection, coarse symbol timing estimation, coarse fractional carrier frequency offset estimation, integer carrier frequency offset estimation, and frame timing estimation. These detection and estimation methods exploit the characteristics of DRM signal structure and pilot cells. Their performance is assessed by simulation with DRM full link simulator and verified with DRM hardware platform based on FPGA.
