Method and device for providing power codificau00c7u00e7o efficient retroalimentau00c7u00e7o in a system of comunicau00c7u00e7o wireless MIMO. A scheme of multiple inputs and multiple outputs (MIMO (multiple input multiple output) which uses the pre coding and feedback in a wireless communication system which includes a transmitter and a receiver.The system can either use a u00fanicapalavra code (CWS single codeword) as a dual code word (DCW double codeword). The pre coding scheme is based on and, in the transmission of a beam directed (beamforming) (txbf). They are considered as combined the retro feeding differential and differential with the reboot...
