Per-antenna rate and power control for MIMO layered architectures in the low- and high-power regimes
14 years 8 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...
