Multi-User Diversity vs. Accurate Channel Feedback for MIMO Broadcast Channels
Niranjay Ravindran, Nihar Jindal
A multiple transmit antenna, single receive antenna (per receiver) downlink channel with limited channel feedback is considered. Given a constraint on the total system-wide channel…

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…
