Simulation and implementation of US QAM-based HDTV channel decoder

The authors present system design considerations and simulation results for a receiver prototype for QAM (quadrature amplitude modulation)-based digital HDTV (high-definition television) systems in the context of current standard deliberations for terrestrial broadcasting. Efforts were concentrated on design choices of the receiver sub-systems for adaptive equalization, and carrier and symbol timing recovery. System performance evaluation results that highlight the effect of the above are presented, and some hardware design examples are also given.<
