Abstract

Disclosed is a method, circuit and system for communicating data. A data value to be transmitted from a data source transmitter or transceiver to a downstream receiver or transceiver may be Shannon mapped, by functionally associated processing/mapping logic, to a point on a shape within a higher dimensional plane. Different portions of the shape, for example branches of a spiral, may be designated by a portion or branch number. Coordinates of the Shannon mapping, or another descriptors, of the Shannon mapped point may be transmitted using analog transmission methods. A set of data values may be Shannon mapped and transmitted to a downstream receiver/transceiver in series. For each set of mapped and transmitted data values, processing logic may calculate a branch ambiguity resolution factor. The branch ambiguity resolution factor for each set of values may be transmitted to the downstream receiver/transceiver before, after or with the data values. Decoding logic associated with the downstream receiver/transceiver may then use the branch ambiguity resolution factor to convert/decode received coordinates associated with the set of values into the data values.
