Collision avoidance system having GPS enhanced with OFDM transceivers

摘要

An object relative status determination system ( 54 ) for a vehicle ( 52 ) includes an orthogonal frequency domain modulation (OFDM) transceiver ( 56 ) that generates an object range signal ( 83 ). The system ( 54 ) may also include a global navigation system (GNS) ( 58 ) that receives a satellite range signal ( 70 ). A controller ( 66 ) is coupled to the OFDM transceiver ( 56 ) and the GNS ( 58 ) and determines object information relative to the vehicle ( 52 ) in response to the object range signal ( 83 ) and the satellite range signal ( 70 ).
