Abstract
An apparatus and method is disclosed of an SMSK/2 device that provides an additional phase state, and having at least three phase changes possible per bit period, as compared with standard SMSK/2 devices. The additional phase state increases the bit time needed for the signals to remerge which increases the euclidean distance defined by the remergence paths. The increase in euclidean distance provides an improved power efficiency and bit error rate (BER).
