ABSTRACT:
A transmitter for a spread spectrum communications system may include a data source, a first multiplier/mixer spreading data from said data source with a first pseudo noise source, a second multiplier/mixer spreading data from said first mixer with a second pseudo noise source, and an RF transmitter. A receiver for a spread spectrum communications system may include an RF receiver, a first matched filter receiving data from said RF receiver, a plurality of phase/frequency shifters receiving a signal from said first matched filter, a plurality of second matched filters receiving data from said plurality of phase/frequency shifters, and an equalizer/decoder receiving signals from said plurality of second matched filters.
