Title: Transmission system and transmission-reception system
Inventor: TSUJII HITOSHI
IPC: G06K17/00
Filed: 2000-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a transmission system and transmission-reception system that can ensure stable and wide range transmission or communication and strong power. SOLUTION: When a reader/writer 13 transmitting signals obtains permission of signal transmission from a control means 2, the digital circuit 7 gives a transmission signal to an analog circuit 8, the analog circuit 8 amplitude- modulates a carrier with the transmission signal, and an antenna 10 receiving the amplitude-modulated signal transmits a transmission wave. Although the phase of the carrier is changed when the carrier passes through the analog circuit 8, a phase shifter means 6 applies a phase shift θ1 to a reference signal fc'(ωt) received from a common oscillation source 3 and gives the resulting signal to the analog circuit 8 in order to compensate the phase shift. Adjusting the phase shift θ1 can set the phase of the transmission wave to be a prescribed standard phase shift θs.  On the other hand, reader/writes 11, 12, 15 that are not transmitting signals emit only a carrier with the same frequency and the standard phase shift θs.
