Per-antenna rate and power control for MIMO layered architectures in the low- and high-power regimes
13 years 10 months ago
—In a MIMO layered architecture, several codewords are transmitted from a multiplicity of antennas. Although the spectral efficiency is maximized if the rates of these codewords...

Error-correcting codes are used to cope with the corruption of data by noise during communication or storage. A code uses an encoding procedure that judiciously introduces redunda...
