dc.description.abstractThe use of multiple antennas for diversity and array
gain may require accurate channel state information (CSI) on
each subcarrier in orthogonal frequency division multiplexing
systems. Such CSI is usually reported from the receiver to the
transmitter, causing a significant amount of feedback signaling
burden. Recent work can noticeably reduce the feedback
signaling burden by exploiting the channel correlation properties
in the frequency domain, but it can be applied to the generation
of a single beam [1]. In this paper, this idea is extended to the use
of multiple beams for spatial multiplexing. Simulation results
show that the proposed scheme can improve the performance
using the same amount of feedback signaling burden or provide
the same performance while noticeably reducing the amount of
feedback signaling burden, compared to conventional schemes.
