Abstract
A technique for segmented frame synchronization for Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) and Integrated Services Digital Broadcasting-Terrestrial Sound Broadcasting (ISDB-TSB) systems, wherein the method comprises receiving a wireless digital signal comprising an Orthogonal Frequency Division Multiplexing (OFDM) frame, further comprising ODFM symbols, in a receiver and wherein the receiver comprises a time de-interleaver, a bit de-interleaver, and a descrambler; filling memory of time de-interleaver and bit de-interleaver by the received wireless digital signal; determining an OFDM segmented frame boundary when memory of the time de-interleaver and bit de-interleaver are full; decoding bits from time de-interleaver and bit de-interleaver using a Viterbi decoder; outputting the Viterbi decoding bits from time de-interleaver and bit de-interleaver when the OFDM segmented frame boundary is detected; obtaining a segmented multiplexing frame boundary upon receipt of the first bit from the Viterbi decoder; and synchronizing the OFDM frame based on the segmented multiplexing frame boundary.
