Παραδείγματα χρήσης DSSS σε μια πρόταση

• In telecommunications, direct-sequence spread spectrum (DSSS) is a spread-spectrum modulation technique primarily used to reduce overall signal interference.
• Three of them preserve the DSSS approach: in the 868/915 MHz bands, using either binary or, optionally, offset quadrature phase-shift keying (QPSK); in the 2450 MHz band, using QPSK.
• However, it is unlike direct-sequence spread spectrum (DSSS) or frequency-hopping spread spectrum (FHSS) in that it does not add any pseudo-random elements to the signal to help distinguish it from noise on the channel, instead relying on the linear nature of the chirp pulse.
• Raleigh solidified the case for OFDM by analyzing the performance of MIMO with three leading modulation techniques in his PhD dissertation: quadrature amplitude modulation (QAM), direct sequence spread spectrum (DSSS), and discrete multi-tone (DMT).
