(a) A power divider PDIV, whose input is the BPSK phase modulation signal at a frequency f, where f is the frequency of the carrier signal. This power divider provides at its output signals i1, i2and i3, with the same frequency f as the input signal. In addition, i1and i3are of...
FIG. 9 is a schematic diagram of an amplitude modulation detector of the kind used in connection with tuning the FM receiver for minimum noise, and with tuning the SCA subcarrier selector for a maximum signal strength; and FIG. 10 is a schematic diagram of an integrating low-pass filter...
ei and eq contain data modulation residuals. Data filter 32 is connected to mixer 26. Mixer 26 produces the Ci signal at its output. Similarly, the Zq and eq signals are applied to the inputs of mixer 26'. As a result, the Cq signal is produced. The Cq signal is transmitted from ...
The invention relates to a device for regenerating a carrier wave from a BPSK or QPSK modulation signal. The device multiplies the received signal by two or four depending on whether it has a BPSK or
