Variable sample rate digital feedback NDA timing synchronization

The evolving digital television broadcasting standard does not standardize the data rate of the transmitted data but instead leaves it completely unspecified. We propose two digital receiver algorithms for the processing of an extended range of variable sample rates. The algorithms are compared in terms of their complexity and performance. One of the algorithms is based on filtering the received samples prior to timing synchronization, whereas the second algorithm increases the sample rate in the timing recovery loop and matched filter. Both algorithms can be implemented causing negligible loss in a DVB receiver.
