Abstract
A BS digital broadcasting receiver which eliminates the uncertainty of an ODU's phase noise-dependent switching point when switching a receiving system. The receiver is provided with a demodulator circuit (A) having a carrier regenerating circuit (A) based on demodulation data in a BPSK modulation section, and with a demodulator circuit (B) having a carrier regenerating circuit (B) based on demodulation data in each time-division modulation section, wherein, when a lock for carriers regenerated by the carrier regenerating circuit (A) is maintained and carriers regenerated by the carrier regenerating circuit (B) is locked, demodulation data, in the BPSK demodulation section and a QPSK demodulation section, output from the demodulator circuit (A) and 8-PSK-modulated demodulation data output from the demodulator circuit (B) are selected by a selector () for outputting.
