摘要
PURPOSE: A digital broadcasting signal receiver using repeated PN sequences and method thereof are provided to improve compensation range of the carrier frequency offset.;CONSTITUTION: The Tss/M delay unit(505) delays the synchronizing segment signal consisting of the repeated pseudo noise sequence for the Tss / M. The complex conjugate unit(510) produces the complex conjugate of the delayed PN sequence. The multiplier(515) multiplies the conjugate complex number calculating in the received PN sequence. The correlation unit(520) produces the correlation value of the delayed PN sequence and the received PN sequence. The highest point detector(530) discovers the position of the repeated pseudo noise sequence. The phase estimator measures the phase of the correlation value calculating.;COPYRIGHT KIPO 2010
