US Patent 8005164 Link adaptation and antenna selection in cooperative multiple access systems

Embodiments of the present invention provide a system comprising a bit stream merger to merge a bit stream of a wireless apparatus with at least one bit stream associated with a wireless device in a common transmit cluster to form a merged bit stream; a time-frequency encoder and interleaver to time-frequency encode and interleave the merged bit stream to generate a coded bit stream; and at least a first and second encoding path, each coupled to the time frequency coder and interleaver, and an antenna array, wherein the first encoding path modulates the coded bit stream according to a first modulation scheme and the second encoding path modulates the coded bit stream according to a second modulation scheme.
