Frequency Acquisition Algorithm for DRM Receiver

In this paper we propose a frequency acquisition algorithm for DRM receiver . Given the parameters of the DRM system and the properties of PC hardware, the requirements for the frequency acquisition are analyzed. Following these requirements an acquisition algorithm using the FFT based on pilot is proposed. This algorithms utilize the continuous frequency correction pilot tones in the DRM signal. Simulation results on different fading channels show that the synchronization scheme suits our needs.
