dc.description.abstractFor a closed-loop transmit (Tx) diversity, the Tx
weights are calculated at a receiver, and fed back to a transmitter.
As the number of Tx antennas increases, the potential gain of
closed-loop Tx diversity may be significant. However, the amount
of feedback information, which is the number of Tx weights
that should be fed back, linearly increases, and the performance
improvement of a closed-loop Tx diversity system may not be
as significant as expected due to delay in the feedback process.
Thus, an efficient Tx weight representation, which can reduce the
amount of feedback information, is needed. In this letter, a Tx
weight vector representation is presented, and its performance is
analyzed. Analysis shows that this weight vector representation,
referred to as basis selection, significantly reduces the amount of
feedback information with little performance degradation.
