Limited-Rate Channel State Feedback for Multicarrier Block Fading Channels
The capacity of a fading channel can be substantially increased by feeding
back channel state information from the receiver to the transmitter. With
limited-rate feedback what state information to feed back and how to encode it
are important open questions. This paper studies power loading in a
multicarrier system using no more than one bit of feedback per sub-channel. The
sub-channels can be correlated and full channel state information is assumed at
the receiver.Comment: Submitted to IEEE Transactions on Information Theor
