徴とする車載受信機。[Scope of Claim for Utility Model Registration] 1. An angle modulator that angle-modulates the main carrier to be transmitted to the in-vehicle receiver using main data and outputs an angle-modulated wave, and a sub-carrier that uses position data to perform MSK.
A road transmitter comprising: an MSK modulator that modulates and outputs an MSK modulated wave; and an AM modulator that performs AM modulation of the angle modulated wave with the MSK modulated wave. 2. An in-vehicle receiver that receives a signal in which the main carrier is angle-modulated with main data, the sub-carrier is MSK-modulated with position data, and the angle-modulated wave is AM-modulated with the MSK-modulated wave, The first part demodulates and outputs the main data.
and a second demodulator that demodulates the MSK modulated wave and outputs position data.
