OFDM RECEIVER AND OFM RECEPTION METHOD

摘要

PROBLEM TO BE SOLVED: To perform waveform equalization with high accuracy when connecting and transmitting ISDB-Ts. SOLUTION: Information for discriminating whether an adjacent segment is a synchronous segment or a differential segment is described in TMCC information in the connection transmission. A receiver refers to the TMCC information, and when the adjacent segment is the synchronous segment, the receiver estimates the transmission characteristic of a transmission path and performs waveform equalization by using an SP signal including an adjacent channel, too. Specifically, a timing control circuit 59 decides whether the SP signal is included in the adjacent channel, and when the SP signal is included, a frequency direction filter 56 performs FIR filtering and corrects a signal of a frequency direction by using not only the SP signal inserted into a frequency channel to be a demodulation channel but also the SP signal of the adjacent channel.
