Instead of using eigen-beamforming approach to increase capacity gain, an optimal pre-weighting scheme is employed in the closed-loop multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (MIMO-OFDM) wireless system design under subcarrier cluster constraint. This scheme adopts an up-link scale weight vector on the space-time(More)
Until now performance analyses about using the Rayleigh plus log-normal (composite) fading effect for relaying systems are still incomplete because it is generally accepted that underlying statistics do not lead to a closed-form expression. In this paper, we refine the analytical framework for cooperative relaying (dual-hop multi-relaying and direct links)(More)
