Abstract

A road side communication equipment is provided crossing over lanes of an expressway, so that a communication processing for toll collection is executed between the road side equipment and an on-board equipment passing a communication area.
The road side equipment sends signals using a 32-bit synchronizing signal for the start slot of each frame and a 16-bit synchronizing signal for subsequent slots of the frame. The on-board equipment receives this to perform signal receiving processing. The received communication signals are then digital-demodulated and entered to a shift register so that the bit pattern is compared in two comparators to detect the synchronizing signal. According to the output from AND circuits, the synchronizing signal is distinguished from the synchronizing signal to determine the received data and receive subsequent data.
