Chirp spread spectrum css technology
WebChirp Spread Spectrum has been used in military and space communication for decades due to the long communication distances that can be achieved; and robustness to interference. Direct Spread Spectrum Systems (DSSS) change the carrier phase of the transmitter in accordance with a high frequency code called chip sequence. WebA chirp spread spectrum (CSS) system uses a chirp signal which changes the instantaneous frequency according to time for spreading a transmission bandwidth. In the CSS system, the transmission performance can be simply improved by increasing the time-bandwidth product which is known as the processing gain.
