On the implementation of MIMO-OFDM schemes using perturbation of the QR decomposition: Application to 3GPP LTE-a systems
Consider a flat-fading Multiple-Input Multiple-Output (MIMO) system. The near-optimum detection problematic has been shown to be efficiently solved through QR Decomposition (QRD...
