Problems solved by technology

The RFED type receiver is a method that can receive multiple channels. It has wideband reception characteristics, so it has the advantage of not requiring channel information, but because the communicable bandwidth is wide, there are other signals near the DSRC terminal band (especially, 5.8 GHz band wireless LAN), there is a high possibility of abnormal operation

Abstract

The invention relates to a multi-channel receiver for DSRC, and the receiver comprises a local oscillator; a mixer which mixes the local oscillation frequencies from the local oscillator with a differential value between a lower channel frequency RF1 from two frequencies inputted by two channels and a higher channel frequency RF2 from two frequencies inputted by two channels, so as to output a medium frequency; and a band-pass filter which allows a frequency signal in a set range of the medium frequency outputted by the mixer to pass.

Description

technical field [0001] The invention relates to a multi-channel receiver for dedicated short-range communication (Dedicated Shortage Range Communication, hereinafter referred to as DSRC). Background technique [0002] The rapid increase in the use of vehicles has caused serious traffic problems. In order to effectively deal with such traffic problems, there is an ITS (Intelligent Transport System) as a system that applies electricity, electronics, information, communication, and automotive technologies to traffic. ITS collects, processes, and processes traffic-related information, weather information, and road status information for national roads, vehicles, drivers, and tourists, and provides information for facilitating traffic and smoothing traffic volume. [0003] As a communication system used for such an ITS, DSRC (Dedicated Short Range Communication) is used, which is a communication method limited to short range. This communication method is as follows: a communicat...
