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 … 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 a much higher bit rate than the original data rate. The resulting transmitted signal resembles bandlimited white noise, … See more • Complementary code keying • Frequency-hopping spread spectrum • Linear-feedback shift register See more • Resistance to unintended or intended jamming • Sharing of a single channel among multiple users 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 WebMay 11, 2013 · The 1Mbps (DSSS/Barker1) / 2Mbps (DSSS/Barker2) modes used 11 chip Barker at 1MBd and used 1 DBPSK / DQPSK symbol in the DSSS symbol multiplexed …
