Impact of CSI on Distributed Space-Time Coding in Wireless Relay Networks
Mari Kobayashi, Xavier Mestre
We consider a two-hop wireless network where a transmitter communicates with a receiver via relays with an amplify-and-forward (AF) protocol. Recent works have shown that sophi…

Quantized vs. Analog Feedback for the MIMO Downlink: A Comparison between Zero-Forcing Based Achievable Rates
Giuseppe Caire, Nihar Jindal, Mari Kobayashi +1
We consider a MIMO fading broadcast channel and compare the achievable ergodic rates when the channel state information at the transmitter is provided by analog noisy feedback or b…
