ABSTRACT:
A method and structure for converting a sequence of binary digits into a sequence of discrete signal values, e.g., phase values, of a modulated carrier signal for data transmission. By introducing additional redundant signal values and coding information in a state-dependent sequential manner, enlarged minimum Euclidian distance between possible signal value sequences is achieved which results in a reduced error probability when maximum-likelihood decoding is applied in the receiver.
