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 .
