Kami menghuraikan skim pengkuantitian saluran-vektor yang sesuai untuk penghantaran berbilang aliran bagi setiap pengguna dalam sistem berbilang-input dan keluaran berbilang pemaksaan sifar (ZFBF) dan sistem keluaran berbilang (MU-MIMO) dengan maklum balas kadar terhingga. Berbilang subset matriks saluran dikuantisasi kepada vektor daripada buku kod vektor rawak untuk maklum balas kadar terhingga. Vektor pengkuantitian dengan perbezaan sudut yang lebih hampir kepada ortogon kemudiannya dipilih dan indeksnya disalurkan semula kepada pemancar. Keputusan simulasi menunjukkan bahawa skim yang dicadangkan mencapai daya pemprosesan purata yang lebih baik daripada yang menyediakan satu aliran bagi setiap pengguna apabila bilangan pengguna aktif adalah lebih kecil daripada bilangan antena pemancar dan bahawa ia menyediakan purata daya pemprosesan yang hampir dengan yang menyediakan satu aliran bagi setiap pengguna. apabila bilangan pengguna adalah sama dengan bilangan antena pemancar.

Abstract: We describe a channel-vector quantization scheme that is suitable for multiple stream transmission per user in zero-forcing beamforming (ZFBF) multiuser multiple-input and multiple output (MU-MIMO) systems with finite rate feedback. Multiple subsets of a channel matrix are quantized to vectors from random vector codebooks for finite rate feedback. The quantization vectors with an angle difference that is closer to orthogonal are then selected and their indexes are fed back to the transmitter. Simulation results demonstrate that the proposed scheme achieves a better average throughput than that serving a single stream per user when the number of active users is smaller than the number of transmit antennas and that it provides an average throughput close to that serving a single stream per user when the number of users is equal to the number of transmit antennas.

AB - We describe a channel-vector quantization scheme that is suitable for multiple stream transmission per user in zero-forcing beamforming (ZFBF) multiuser multiple-input and multiple output (MU-MIMO) systems with finite rate feedback. Multiple subsets of a channel matrix are quantized to vectors from random vector codebooks for finite rate feedback. The quantization vectors with an angle difference that is closer to orthogonal are then selected and their indexes are fed back to the transmitter. Simulation results demonstrate that the proposed scheme achieves a better average throughput than that serving a single stream per user when the number of active users is smaller than the number of transmit antennas and that it provides an average throughput close to that serving a single stream per user when the number of users is equal to the number of transmit antennas.
