An enrichment technique that produces a spread spectrum modulated signal from a short length spreading sequence with characteristics similar to a spreading sequence of much greater length. The present technique allows for shorter length spreading sequences to be utilized with similar Power Spectral Density (PSD) and probability of reception properties to that of longer spreading sequences. Other advantages of the present technique, with shorter spreading sequences, includes shorter acquisition times due to shorter spreading sequences, preamble signal identification, and on-air transmit time reduction. |
