WebMar 23, 2024 · However, the CSS scheme is more suitable than the DSSS scheme for high-mobility IoT services because of its robustness against the Doppler effect. We discuss various solutions, such as the preprocessing of Doppler effect and avoidance of packet collision, to enhance the performance of the DSSS and CSS schemes.

WebIEEE 802.11b supports four data rates viz. 1 Mbps, 2 Mbps, 5.5 Mbps and 11 Mbps. DSSS is used to provide support for 1 Mbps and 2 Mbps data rate. CCK for 5.5 and 11 Mbps while OFDM is used for higher data rate … WebUnlike a conventional communication system, however, a DSSS system does have a certain resistance against narrowband interference, as the interference is not subject to the process gain of the DSSS signal, and hence the signal-to-interference ratio is improved. In frequency modulation (FM), the processing gain can be expressed as
