Fuyun Ling: Method and apparatus for coherent communication in a spread-spectrum communication system. Motorola, Richard A Sonnentag, Shawn B Dempster, July 12, 1994: US05329547 (135 worldwide citation)

A method and apparatus is provided for encoding and decoding to facilitate coherent communication. In encoding, reference symbols are inserted into a stream of input data symbols to form a reference coded stream of input data symbols. Subsequently, the reference coded stream of input data symbols ar ...

David D Falconer, Fuyun Ling: Method and apparatus for using orthogonal coding in a communication system. Motorola, Shawn Dempster, April 20, 1993: US05204874 (131 worldwide citation)

A method and apparatus is provided for encoding and decoding. In encoding, bits (202) are encoded (204) into symbols (206) such that maximum likelihood decoding is facilitated. Groups of symbols (206) are translated by either interleaving by group each group within a block (208) and subsequently der ...
