Circuit for capturing absolute phase synchronization

摘要

A small-scale absolute-phasing synchronization capturing circuit for absolute phasing of a received signal by selectively transmitting a baseband signal demodulated through a demodulator (1), a baseband signal subjected to phase rotation through a remapper (11), a baseband signal output from a first inverting means, a baseband signal output from a second inverting means based on the phase angle of the received signal relative to the phase rotation of the transmission signal. The most significant bit in the demodulated baseband signal and the most significant bit in the baseband signal subjected to phase rotation through the remapper (11) are extracted and a frame synchronization signal is captured according to the extracted significant bit.
