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...

A Graph-Based Approach to Multi-Cell OFDMA Downlink Resource Allocation
— A novel, practical and low-complexity multi-cell OFDMA downlink channel assignment method using a graphbased approach is proposed in this work. The inter-cell interference (ICI...
