Multi-Frame Distributed Protocol for Analog Network Coding in Slow-Fading Channels
The wireless network scenario here is based on N users that communicate one with the others through a central relay node by adopting the Analog Network Coding (ANC) paradigm. In th...

Two-Slot Channel Estimation for Analog Network Coding Based on OFDM in a Frequency-Selective Fading Channel
—Recently, broadband analog network coding (ANC) was introduced to utilize high-data rate transmission over the wireless – frequency selective fading – channel. However, ANC ...

A Fair Radio Resource Allocation Scheme for Ubiquitous High-Data-Rate Coverage in OFDMA-Based Cellular Relay Networks
—The provision of very high data rates in a ubiquitous and fair manner throughout the service area is a great challenge for 4G and beyond-4G wireless networks. Towards that end, ...
