However, direct sequence spread spectrum requires bi-polar signaling, which is not possible with direct detection and several solutions exist, such as, biased and differential transmission. In this work, we investigate the performance of direct-sequence spread spectrum time division multiple access with...

What Does Direct Sequence Spread Spectrum Mean? Direct sequence spread spectrum (DSSS) is a transmission technology used in local area wireless network transmissions. In this technology, a data signal at the sending station is combined with a high data rate bit sequence, which divides user data ...
aDirect sequence spread spectrum transmissions (DS-SS) are now widely used for secure communications,as well as for multiple access. They have manyinteresting properties, including low probability of interception. Indeed, DS-SS transmitters use a[translate]...
