Chirp carriers
WebFeb 20, 2009 · Due to the excellent autocorrelation and keen-edged time properties of the chirp pulses generated by the chirp pulse compression technique, we applied this kind of technique to Ultra-Wideband Radio Communication and designed a CSS-BOK-UWB wireless communication system. Webmultiple chirp-rate shift keying (MC-MCrSK), each symbol time include two carriers (up-chirp and down-chirp), so it can get a higher data rate than signal carrier system. The scheme can support multiuser to communication based on chirp-rate combination order. Multipath effect of underwater acoustic would lead receiver to produce erroneous judgment.
