<p>A system for transmitting digital data messages between a plurality of stations using a common communications channel is disclosed. The data messages are assembled into data packets which include address and control information. The data packets are then transmitted from the stations over the common channel using appropriate data representative waveforms or modulation. A composite waveform representative of the data packets including potentially time overlapping data packets are received and processed to decode at least one packet. The waveform representative of the at least one decoded packet is reconstructed and subtracted form the received composite waveform to obtain a residual waveform. The residual waveform is then further processed to attempt to decode at least one further packet.</p> |
