Abstract :
Based on the fact that the effective bandwidth of regenerated RF signals of high density digital versatile disk (DVD) systems is about 1/4 T where T is the symbol period, we propose a DVD receiver that can recover source data with rate 1/T after 1/2 T sampling. This receiver employs an interpolator that increases the data rate to 1/T. It is shown that the proposed receiver can perform like conventional receivers with a sampling rate 1/T at the expense of a minor increase in computation. Since the proposed receiver can recover the data at twice of the A/D convertor rate, it should be very useful for high-speed data recovery
