¿µ¹®³»¿ë¿ä¾à In this standard, By using a hybrid waveform, OCC systems can simultaneously transmit both low-rate and high-rate data streams. While the low-rate data stream is used for setting up the communication link between vehicles, the high-rate data stream is used for high-speed data transmission. New modulation scheme such as camera-on-off-keying (C-OOK) is proposed to modulate low-rate and data stream. For the high-rate data stream, single-carrier modulation or multiple-carrier modulation, such as the proposed dimmable-spatial-8-phase-shift-keying (DS8-PSK) can serve as viable solutions.
