For you case $f_0 =-f_ {limit}$.

WebFeb 1, 2024 · As a broadband signal, chirp carriers have a certain tolerance for the frequency offset and are robust for Doppler. In summary, it will be easier to achieve time and frequency synchronization in comparison with traditional DSSS and FHSS and will be more suitable for underwater acoustic communication. WebAs for its latest innovation, even though some airlines in the industry’s early days experimented with ways to allow passengers to fully recline, Geraghty said that Air New Zealand appears to be the “first to actually put this offering onboard an aircraft.” Chris Agee April 14th, 2024

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.
