Abstract
In order to recover the original audio modulation samples when using a continuous code change, sampled data, spread spectrum waveform structure, a dedicated message matched filter is used to process data from multiple emitters within the same range interval. The dedicated message matched filter is matched to an incoming signal only at the precise time of the message epoch. The matched filter coding corresponding to the arrival time of message epochs as derived from synchronization acquisition circuitry is rapidly switched so that one dedicated message matched filter can be used to process data from multiple users simultaneously.
