Title: Double side band amplitude modulation phase duplex transmission system
Inventor: MIZUNO SHINZO
IPC: H03D1/00
Filed: 1991-11-18
Abstract: PURPOSE:To attain 2-channel transmission per one carrier by applying amplitude modulation to a 1st or 2nd carrier with a prescribed phase difference by a 1st or 2nd information signal and sending the modulated signal while the carrier is being suppressed and allowing a receiver side to apply synchronization detection with a 1st or 2nd demodulated carrier generated based on a specific phase difference of each phase of each carrier. CONSTITUTION:A caller station 10 generates a 1st modulation carrier and a 2nd modulation carrier whose phase angle leads by +alpha and applies amplitude modulation by using 1st and 2nd information signals. Each BPF is used to output double side attended with a 1st modulation carrier on one hand and to output double side band with a 2nd modulation carrier suppressed therein on the other hand to a transmission medium A. A receiver R uses a crystal BPF 11 to extract the 1st modulation wave and uses a phase comparator 12 and pi/+alpha, pi/2 phase shifters 15, 16 or the like to generate 1st and 2nd demodulated carriers. Synchronization detection circuits 17, 18 use both waves to detect a reception wave and to output the 1st and 2nd information signals. Thus, 2-channel transmission per one carrier is attained.
