DSSS - Direct Sequence Spread Spectrum

In 802.11 standards, three different modulation/transmission methods are used to transmit wireless signals: 1) Frequency Hopping Spread Spectrum, or FHSS; 2) Direct Sequence Spread Spectrum, or DSSS, and 3) Orthogonal Frequency Division Multiplexing, or OFDM. These techniques are used for several reasons, including the reduction of natural interference, noise and jamming, and prevention of detection and interception. In this lesson, I will focus on DSSS.
