ABSTRACT:
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.
