Abstract:
1. A system for decoding a three phase waveform, comprising: a receive stage configured to receive the three phase waveform having data encoded thereon from a distribution line in a power distribution system and separate the three phase waveform into a first waveform, a second waveform, and a third waveform, wherein the data is encoded on one or more of the first waveform, the second waveform, and the third waveform; an analog-to-digital converter configured to convert the first waveform, the second waveform, and the third waveform into a first digital signal, a second digital signal, and a third digital signal; a first gain stage, a second gain stage, and a third gain stage, wherein each of the first gain stage, the second gain stage, and the third gain stage is configured to adjust an amplitude of the first digital signal, the second digital signal, and the third digital signal, wherein each of the first gain stage, the second gain stage, and the third gain stage are further configured to combine by summation the amplitude adjusted digital signals into a first gain adjusted combined signal, a second gain adjusted combined signal, and a third gain adjusted combined signal wherein the data is encoded on one or more of the first gain adjusted combined signal, the second gain adjusted combined signal, and the third gain adjusted combined signal; and a signal extraction stage configured to extract signal comprising the data from the first gain adjusted combined signal, the second gain adjusted combined signal, and the third gain adjusted combined signal.
