Phase-Shifting Encoding For Signal Transition Minimization

Abstract:

A method of encoding a stream of data bits includes encoding a bit 1 of the data stream as a first symbol if a bit immediately preceding the bit 1 is encoded as 0 and a bit of the data stream immediately succeeding the bit 1 is 0, encoding the bit immediately succeeding the bit 1 as 1, encoding a bit 0 of the data stream as a second symbol if a bit immediately preceding the bit 0 is encoded as 1 and a bit of the data stream immediately succeeding the bit 0 is 1, and encoding the bit immediately succeeding the bit 0 as 0.
