Abstract :
Channel equalization techniques for full-digital high definition television (HDTV) systems are investigated. Conventional equalization methods are surveyed and a variable step size least mean square (VS-LMS) algorithm using the simple time constant concept is proposed. Several equalization techniques for HDTV systems are simulated for various channel models, and their characteristics are analyzed. Also the simulation results of the equalizer using fixed-point operations are shown
