In this work, we present a method to generate quantization codebooks tailored for efficient implementation of beamforming-based Multiple-Input Multiple-Output (MIMO) transmissions. The proposed codebooks can reduce computational requirements significantly, making feasible an efficient architecture for a real-time transmit beamforming and receive combining MIMO orthogonal frequency division multiplexing (OFDM) system. Simulation results validate the proposed codebook construction method and architecture.86 p.application/pdfengCopyright is held by the author, unless otherwise indicated.
