Abstract
In electromagnetic communication different data streams share a common communication medium by being multiplexed. Each individual data stream employs its own unique modulation waveform set. A receiver for a given data stream comprises correlators for the waveforms in the corresponding modulation waveform set. If the waveforms in all the different modulation waveform sets are not orthogonal, then the output of correlators at a given receiver will not only contain the desired information components of the data stream to which they are matched but also components from the other data streams. This is termed cross-talk. Processors are provided which are responsive to the outputs of all waveform correlators. They provide a means for detecting the original data stream information in the presence of cross-talk. When there is no noise in the communication transmission the processors cancel the cross-talk.
