Digital data is encoded into a series of analog waveforms, called symbol waveforms, created as the result of interference of sinusoidal wave interference patterns. Each of these symbol waveforms is an encoded version of N-bits of data. These encoded symbol waveforms is an encoded version which are very different, in both appearance and in propagation properties, from traditional voltage state signaling or pulse codes. The encoded symbol waveforms are formed by generating and superimposing a set of analog sinusoidal waves, where the gain and phase shift of each wave is computed so as to provide, in combination, a unique interference pattern that can be recognized, via signal processing techniques, by a detector and then decoded. The symbol waveforms are computed so that successive symbol waveforms seam together to form a smooth continuous AC analog signal that does not itself generate interference frequencies, can be bandpass filtered, and is suitable for long distance propagation. The transmission technology of the present invention is applicable to, inter alia, a digital communications device or system. |
