Abstract :
In this paper the channel estimation methods are investigated for DRM system. Enhanced channel estimation algorithm adaptable for DRM based on Wiener interpolation is developed. The presented Wiener filter interpolation algorithm simplifies the system by composing the two-dimension filter into two one-dimension filter. Performance comparison of the proposed algorithm with the windowed DFT is also presented. Simulation and results show that Wiener interpolation algorithm outgoes the windowed DFT algorithm and Wiener filter algorithm can well fulfill the requirement of DRM systems.
