摘要：
An orthogonal frequency division multiplexing wireless communication terminal, that communicates with a base unit, obtains a set of analog coefficients by transforming a transmit spatial covariance matrix, modulates the set of analog coefficients onto multiple channels to form a feedback waveform, and transmits the feedback waveform to the base unit.
