Digital synthesized wideband noise-like waveform

Apparatus for generating a digitally synthesized noise-like waveform that may be used to modulate and demodulate communication data, said apparatus comprising:

• a seed generator for generating a predetermined random seed input;
• a read only memory look-up table comprising pseudo-random digital samples having predetermined statistics;
• a sequence generator coupled between the seed generator and the read only memory look-up table for generating a pair of pseudo-random sequences in response to the predetermined seed input that address the read only memory look-up table and output a pair of pseudo-random samples;
• processing means coupled to the read only memory look-up table for combining the pair of pseudo-random samples with communication data to generate a spread spectrum waveform;
• and
• modulation means coupled to the processing means for processing the spread spectrum waveform to generate a modulated output signal having a digitally synthesized noise-like waveform.
