Kurzfassung englisch:
A timing recovery system for ATSC standard
HDTV receivers is presented. The proposed solution operates
at baud rate, thereby enabling use of a symbol-spaced channel
equalizer and simplifying the demodulator architecture. The
selection of a Farrow interpolator further lowers the design
complexity.
A Mueller and Muller timing error detector is used in nondata-
aided (NDA) mode, and timing recovery is therefore not
restricted to training sequences. This leads to favorable
control characteristics, obviates the need for a training
sequence detector and reduces the lock-in time.
The design utilizes components with non-ideal characteristics,
and yet satisfies the performance requirements at a low
implementation and operational cost.
