Abstract

A communication system includes a plurality of subscribers each of said subscribers having a transceiver including a transmitter and a receiver. In the system there are means coupled to each of said transceivers to enable said transmitter to transmit a unique waveform having a predetermined time, frequency and phase code and each transceiver includes means coupled to the receiver to enable anyone of said subscribers to receive any transmitted waveform while others of the subscribers including those receiving said waveform can simultaneously transmit other unique waveforms whereby any subscriber can receive any transmitted waveform while simultaneously transmitting another waveform.
