A Transmission and Receiving System using an One-chip Microcomputer for Short Range Communication

摘要

The short range communication systems often require low-power consumption performance and low cost rather than high speed data transmission systems. This report proposes a low-power radio communication device using an one-chip microcomputer for short range transmission and receiving system providing low cost and low-power consumption. In the transmitter, pulses for carrier signal are generated by the one-chip microcomputer, and filtered and radiated by an antenna. In the receiver, a radio IC detects the received signal and the one-chip microcomputer processes digitally. The proposed transmitter and receiver are demonstrated, and its performance is evaluated by experiment.
