On the costs of channel state information

We study the capacity of fading channels with no CSI at both the transmitter and the receiver. We focus on the low SNR regime, and study the impact of channel memory on the capacity. While the current results on these issues are based on various limiting assumptions, we use a new approach of asymptotic analysis to capture the relation among the key system parameters, and depict the continuum between the extreme cases.
