1. An apparatus for decoding N spread spectrum pseudo randomly coded signals in the form of a single composite CW signal to form a plurality of pulses each containing all the information in one of said N signal, comprising:

  • means for adjusting the bandwidth of said composite signal to a predetermined bandwidth;

    a tapped delay line for serially receiving said CW signal of said predetermined bandwidth;

    means for storing a pseudo random reference code corresponding to a preselected code segment of one of said N spread spectrum signals;

    comparison means for detecting correlation between said reference code and said one of said N signals;

    means for generating a pulse containing all the information in a segment of one of said N signals, said segment corresponding to the total delay time of said tapped delay line, the position of said pulse indicative of the degree of synchronization between said reference code and said first signal; and

    means for changing said reference code to one associated with another of said N signals;
