Abstract
This paper presents results of computer simulations and laboratory tes ts to investigate various digital techniques (i.e., trellis coded QAM, vestigial sideband (VSB) modulation, orthogonal frequency division mu ltiplexing (OFDM), and adaptive equalization) proposed for Advanced Te levision (ATV) terrestrial broadcasting. The performance of these chan nel coding and modulation techniques, in the presence of various inter ferences (i.e., Gaussian noise, ATV and NTSC co-channel interference) and in a multipath distortion environment, is evaluated and compared. The effects of ATV interference into NTSC systems are also investigate d.
