WebThe following are some disadvantages of Direct Sequence Spread Spectrum or DSSS: The Direct Sequence Spread Spectrum or DSSS system takes large acquisition time; that's why its performance is slow. It … WebApr 12, 2024 · Direct-sequence spread spectrum (DSSS) is a modulation technology that essentially spreads radio waves around. This helps to reduce interference from other devices. Orthogonal frequency-division multiplexing (OFDM) sends a number of small waves at a slow speed so that each wave contains part of the signal.
