Aliasing Variable Sample Rate DVB

Abstract The evolving digital television broadcasting standard does not standardize the data rate T of the transmitted data but instead leaves it completely unspecied We propose two digital receiver algorithms for the processing of an extended range of variable sample rates T s based on a timing synchronization algorithm producing syn chronized samples at rate MT where M is variable The algorithms are compared in terms of their complexity and performance One of the algorithms is based on ltering the received samples prior to timing synchronization and choosing M whereas the second algorithm also uses the sample rate T in timing recovery loop and matched lter depending on TT s and thus avoids the necessity of preltering Both algorithms can be implemented causing negligible loss in a DVB receiver This paper was published in part at Globeco
