Title: Receiver for composite modulation wave
Inventor: FUJIMOTO ATSUSHI
IPC: H04L27/38
Filed: 1991-11-26
Abstract: PURPOSE:To reduce deterioration of a speech quality by receiving both of an output signal of a phase detector and a receiving signal strength output, outputting a signal being proportional to its level difference, and outputting roughly independently two signals by one carrier wave. CONSTITUTION:A receiving signal 1 is applied to a limiter amplifier 2, and an RF signal of prescribed amplitude being an output signal of the limiter amplifier 2 is applied to a phase detector 3. As for an output signal 6 of this phase detector 3, a noise caused by amplitude modulation is superposed on a demodulating signal of angle modulation. On the other hand, an RSSI signal 4 being a receiving signal strength output signal outputted from the limiter amplifier 2 passes through a delaying circuit 5 for compensating a delay time by the phase detector 3, and thereafter, is allowed to branch. Subsequently, one of them, and the other are applied to a noise eliminating circuit 8, and an anti-logarithmic amplifier 9, respectively. An output signal 7 of this circuit 5 is almost the same signal as a noise caused by amplitude modulation, and by taking a level difference of the signal 6 and the signal 7 by the circuit 8, a demodulating signal 10a of amplitude modulation is obtained.
