Abstract :
This paper reports an effective channel estimation technique for use in DVB-T receivers with asynchronous sampling clock. When compared with a 2-D interpolation method, the proposed approach can significantly improve the receiver performance tested with the on-air received signals. In addition, we also describe our observation of the channel response during experiments.
