Abstract
We propose a new adaptive multiple-input multipleoutput
(MIMO) transmission scheme that can work with partial
channel information. Utilizing the information on dominant eigendimensions
of the channel correlation matrix, the proposed
scheme reduces the amount of channel information required for
adaptive transmission without noticeable performance
degradation. It is analytically shown that the proposed scheme can
minimize the performance loss by properly choosing the number
of eigen-dimensions of the channel correlation matrix. Simulation
results show that the proposed scheme is quite applicable to
practical systems where quantized channel information is utilized.
