    摘要: A method of transmission over multiple wireless channels in a multiple antenna system includes storing channel modulation matrices at a transmitter; receiving quantized channel state information at the transmitter from plural receivers; selecting a transmission modulation matrix using the quantized channel state information from the stored channel modulation matrices; and transmitting over the multiple channels to the plural receivers using the selected transmission modulation matrix. In another embodiment, the method includes storing, at one or more receivers, indexes of modulation matrices generated by a capacity enhancing algorithm; upon a selected one of the one or more receivers receiving a transmission from the transmitter, the selected receiver selecting a modulation matrix from the stored modulation matrices that optimizes transmission between the transmitter and the selected receiver, the selected receiver sending an index representing the selected modulation matrix; and receiving the index at the transmitter from the selected receiver.

    摘要: A CSI vector quantizer (VQ) system is provided for time-correlated channels. The VQ system operates a receiver forwarding quantized channel state information in the form of indices and a transmitter predicting channel state change. The VQ system is aimed at feedback channels, in which bit errors, erasures and delays can occur. The VQ system uses transmitter-side channel prediction algorithms that work with the quantized CSI information and allow the system to recover from feedback channel transmission errors, erasures and delays. Moreover, the techniques can be used to lower the required feedback rate, while keeping the system's throughput at the required level.
