New Spreading Transforms for Fading Channels

Overview This paper introduces a new class of symbol-spreading transforms that are well-suited for use in error-control coding systems operating in fading channels. These unitary transforms have the property that they allow for the unambigous determination of input symbols from just a single correctly received output symbol. The transforms can be represented using factor graphs that allow for "fast" encoding.
