Signal space diversity for spatial multiplexing
— When channel state information is available at the transmitter, we can diagonalize a MIMO channel with SVD transceivers. However, outage of the weaker eigenchannels limits the ...

Transmission Over Slowly Fading Channels Using Unreliable Quantized Feedback
We study the problem of maximizing the expected rate over a slowly fading channel with quantized channel state information at the transmitter (CSIT). This problem has been recentl...
