ABSTRACT:
A digital advanced television (ATV) receiver includes a multi-tap feedforward filter for reducing NTSC co-channel interference in a received ATV signal. A complementary Tomlinson precoder is used to compensate the transmitted ATV signal for inter-symbol interference (ISI) created in the receiver by the feedforward NTSC rejection filter. Data components of the transmitted signal are non-linearly precoded while synchronization components are linearly precoded to improve sync recovery S/N performance in the receiver.
