  • Hybrid codebook design for wireless systems
    Patent number: 9088872
    Abstract: Briefly, in accordance with one or more embodiments, a codebook for wireless transmissions may be generated by dividing a codebook into a fixed set of codewords and an adaptive set of codewords. The adaptive set of codewords may be scaled to cluster together and then rotated to be centered or nearly centered about a target. The adaptive set of codewords may then be merged with the fixed set of codewords to provide a hybrid codebook. A codeword from the hybrid codebook may be selected for precoding a transmission to provide a minimum, or nearly minimum, quantization error.

  • Block time domain equalizer for time reversal-space time block code system and method for encoding and equalizing received signal in the block time domain equalizer
    Patent number: 7970046
    Abstract: Provided is a block Time Domain Equalizer (TDE) for a Time Reversal-Space Time Block Codes (TR-STBC) system. The block TDE comprises a block equalizer which generates an output based on an equalizer tap weight with respect to two consecutively received blocks, an equalizer tap weight updating unit which generates an error vector based on the output and the equalizer tap weight and updates the equalizer tap weight using the error vector, and a signal processing unit which processes the output into a digital signal wherein zero padding is eliminated from the output.
