Method and apparatus for quantization and detection of power loadings in MIMO beamforming systems

摘要

A telecommunication system has a wireless transmitter that transmits data stream signals via multiple channels over a plurality of antennas, the transmitter having a power controller that selects transmission power loading per channel. The telecommunication system further has a wireless receiver that receives data stream signals from the transmitter, and the receiver has a detector that estimates power loading selections of the transmitter. The controller further quantizes the power loading values, and the detector uses the quantized power loading values to automatically estimate power loading selection by the transmitter.
