Abstract
A MIMO wireless communication system employing a variable size preceding codebook is provided. The size of the codebook may be determined by the quality of the wireless transmission channel between a transmitter and a receiver associated with the MIMO wireless communication systems or some other codebook selection criteria. A larger codebook can be employed when the channel quality is high, allowing for significant gains in overall system throughput. In contrast, a smaller codebook can be employed when the cannel quality is poor, so that the added channel overhead associated with a larger code book does not reduce the channel efficiency under circumstances in which a larger codebook would not significantly improve system throughput.
