摘要针对美国ATSC标准的多电平残留边带调制(8VSB)传输系统,研究并提出一种新的相位同步半盲算法,并通过sys- temview仿真对DD算法、盲算法和半盲算法在不同信噪比下的性能作了比较,验证了半盲算法的优越性。 A new semiblind algorithm for phase synchronization used in ATSC 8-VSB transmission system is presented in this paper. The performances of decision-directed, blind and semiblind algorithms under different SNRs are compared by simulation with Systemview, which proves the advantages of semiblind algorithm.
