DECOUPLED DATA-AIDED CARRIER TRACKING LOOP AND SYMBOL TIMING RECOVERY LOOP

摘要

A receiver is an ATSC (Advanced Television Systems Committee)-receiver and comprises a staggered quadrature amplitude modulator for providing an staggered quadrature amplitude modulated (SQAM) signal from a received signal; an equalizer and a data-aided symbol timing recovery (STR) loop. The equalizer operates outside of the data-aided symbol timing recover loop.
