ABSTRACT:
A method for achieving high bit densities in a direct-sequence spread spectrum communication system. The first step is to create a first pseudo-noise code with a given sequency value. The information signal is then spread by modulating the information signal with the pseudo-noise code where the pseudo-noise code used has a sequency value equal to that of the value of the signal. The information signal is then despread and the value of the information signal is determined by the sequency value of the pseudo-noise code used to demodulate the signal.
