Synchroner QPSK-Demodulator for Digital Satellite broadcasting receivers at 12 GHz
Abstract
The signal and noise behavior of various synchronous QPSK demodulators is presented. Subsequently the construction and experimental results of a QPSK demodulator, which generates the transmitted digital information from the 12-GHz input signal without conversion to an intermediate frequency, are described.
