In telecommunications, direct-sequence spread spectrum (DSSS) is a spread-spectrum modulation technique primarily used to reduce overall signal interference. The direct-sequence modulation makes the transmitted signal wider in bandwidth than the information bandwidth. After the despreading or … See more 1. DSSS phase-shifts a sine wave pseudorandomly with a continuous string of chips, each of which has a much shorter duration than an information bit. That is, each information bit is modulated by a sequence of much … See more Direct-sequence spread-spectrum transmissions multiply the data being transmitted by a pseudorandom spreading sequence that has … See more • The United States GPS, European Galileo and Russian GLONASS satellite navigation systems; earlier GLONASS used DSSS with a single spreading sequence in conjunction with See more • Civil Spread Spectrum History See more • Resistance to unintended or intended jamming • Sharing of a single channel among multiple users • Reduced signal/background-noise level hampers interception See more • Complementary code keying • Frequency-hopping spread spectrum • Linear-feedback shift register See more WebDec 4, 2024 · This is the MCQ in Wireless LANs from the book Data Communications and Networking 4th Edition by Behrouz A.
