Direct-sequence spread spectrum (DSSS) is a method of transmitting radio signals by spreading the data across a wide band of frequencies using a spreading code. This type of spread spectrum technology is typically used to improve the resistance of communications systems to external interference and jamming, and can also provide increased privacy and security.
In the case of drones, DSSS can be used in the transmitter to improve the reliability and security of the communication link between the drone and its remote control or ground station. DSSS is a popular choice for drone communication systems due to its ability to provide a high data rate and robustness against interference.
One of the key advantages of DSSS is its ability to resist interference from other radio sources, such as other drones or nearby wireless networks. By spreading the data across a wide band of frequencies, DSSS can avoid interference from other signals and maintain a stable communication link.
Another advantage of DSSS is its security. By using a spreading code, DSSS can provide increased privacy and security for the communication link. It is difficult for an unauthorized third party to intercept or jam the signal because the data is spread across a wide band of frequencies.
In addition to its resistance to interference and improved security, DSSS can also provide a high data rate. This makes it well suited for applications such as video transmission from a drone.
In conclusion, DSSS is a valuable tool for improving the reliability and security of communications systems, especially in the case of drones. By spreading the data across a wide band of frequencies and using a spreading code, DSSS can resist interference and provide a high data rate for video transmission.
