Abstract:
1. An apparatus for a wireless communication station that communicates symbols, said apparatus comprising: a symbol provider configured to provide a first symbol and a second symbol during at least a first symbol time period, the second symbol created with a phase-offset relative to the first symbol, the first symbol being a member of a first symbol set and the second symbol being a member of a second symbol set, the first symbol set and the second symbol set being from different constellations that are phase-offset from each other; an encoder adapted to receive the first symbol and the second symbol provided by said symbol provider as input symbols and encode the first symbol and the second symbol as a code block, wherein each of the input symbols of the code block are from a different constellation, said encoder configured to space-time block code the first symbol and the second symbol and wherein successive encoded symbols provided by said encoder are alternately taken from the different constellations, such that phase-offset between the successive encoded symbols are of a reduced dynamic range.
