What is DS-SS (Direct-sequence spread spectrum)?

Direct-sequence spread spectrum (DSSS) is a spread-spectrum modulation method essentially utilized to decrease generally signal impedance. Some reasonable and compelling utilization of DSSS incorporates the code-division multiple access (CDMA) strategy, the IEEE 802.11b determination utilized in Wi-Fi networks, and the Global Positioning System. The direct-sequence modulation makes the transmitted signal more extensive in bandwidth than the data bandwidth.
