Abstract:
In this paper, we describe novel channel estimation schemes for terrestrial digital multimedia broadcasting (T-DMB) receivers and present further results on their performance under fading channels. In order to improve the performance, novel channel estimation schemes utilize the weighted moving average. Numerical results show that the novel channel estimation schemes outperform the conventional scheme with approximately 2~3dB in the symbol error rate performance under fading channels.
