Robust transmit processing for frequency-selective fading channels with imperfect channel feedback
Reliable channel state information at the transmitter (CSIT) can improve the throughput of wireless networks significantly. In a realistic scenario, there is a mismatch between th...

Outage Behavior of Discrete Memoryless Channels Under Channel Estimation Errors
Classically, communication systems are designed assuming perfect channel state information at the receiver and/or transmitter. However, in many practical situations, only an estim...

Channel Diversity in Random Wireless Networks
The goal of this paper is to explore the benefits of channel diversity in wireless ad hoc networks. Our model is that of a Poisson point process of transmitters, each with a recei...
