Title:
DIGITAL SATELLITE BROADCAST RECEIVER
Document Type and Number:
Japanese Patent JP3660969
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a digital satellite broadcast receiver that can quickly conduct re-synchronization in the case of site changeover.
SOLUTION: A site diversity control circuit 5 detects a super frame after a predetermined number of frames from a site diversity execution instruction, a digital filter 9 is set to a gain for high speed acquisition to recover a carrier as the reception of the 8 PSK modulation system for the carrier recovery just after the detection of a TMCC information block in the detected super frame, acquires a frame identification synchronous pattern in succession to the TMCC information block in the super frame, an absolute phase is calculated in the frame identification synchronous pattern block and a gain in a normal reception state is set to the digital filter 9.
