Abstract
Disclosed is a high-speed controller area network (CAN) communication system, which is compatible with a CAN communication system, using passband modulation. The system includes: a high-speed CAN controller configured to provide a standard CAN transmission bit stream and a high-speed CAN transmission bit stream; and a high-speed CAN transmitter configured to synthesize a passband CAN signal obtained by modulating the high-speed CAN transmission bit stream in a passband and a standard CAN signal based on the standard CAN transmission bit stream and to transmit it to a CAN bus.

A high-speed controller area network (CAN) communication system, which is compatible with a CAN communication system, using passband modulation, the system comprising:
- a high-speed CAN controller configured to provide a standard CAN transmission bit stream and a high-speed CAN transmission bit stream;
- and
- a high-speed CAN transmitter configured to synthesize a passband CAN signal obtained by modulating the high-speed CAN transmission bit stream in a passband and a standard CAN signal based on the standard CAN transmission bit stream and to transmit it to a CAN bus.
A CAN communication system including a CAN transmitter and a CAN bus, the system comprising:
- the CAN transmitter configured to receive the first bit stream and the second bit stream, generate the first bit stream as a standard CAN signal, modulate the second bit stream to generate a passband CAN signal, and transmit a transmission signal obtained by adding the passband CAN signal to the standard CAN signal;
- the CAN bus configured to deliver the transmission signal;
- and
- a CAN receiver configured to receive the transmission signal,
- wherein the first bit stream is composed of dominant bits and recessive bits according to the CAN standard.
