Why is direct sequence spread spectrum (DSSS) the most commonly used type of spread spectrum?

Direct Sequence Spread Spectrum (DSSS) is widely recognized for its ability to facilitate high data rates while maintaining ease of implementation, which is why it is often chosen in various communication systems. The technique works by spreading the signal over a wide frequency band, utilizing a spreading code that increases the signal's bandwidth. This process not only enhances the security of the transmission by making it less susceptible to interception but also enables better resistance to interference and multipath fading, which are common issues in wireless communications.

The ease of implementation stems from the availability of compatible technologies and software that simplify the integration of DSSS into existing systems. Furthermore, its capability to support high data rates makes DSSS particularly attractive for applications that require efficient and speedy communication, such as in wireless networking and mobile telecommunications. These combined advantages make it a preferred choice, especially when considering the demands for both performance and reliability in modern communication systems.
