摘要:
At least two information waveforms are transmitted over the same communications channel using Lincompex techniques. Each of the information waveforms are modulated using Lincompex techniques to generate compressed information waveforms and associated control tones. The compressed information waveforms have the same frequency band. The compressed information waveforms and associated control tones are arithmetically combined, and transmitted over a transmission medium. These signals are then received from the transmission medium. A plurality of Lincompex expanders demodulate the received signals using Lincompex techniques and one of the associated control tones.
