Distributed Learning for Channel Allocation Over a Shared Spectrum
S. M. Zafaruddin, Ilai Bistritz, Amir Leshem +1
Channel allocation is the task of assigning channels to users such that some objective (e.g., sum-rate) is maximized. In centralized networks such as cellular networks, this task i…
The Interference Channel Revisited: Aligning Interference by Adjusting Receive Antenna Separation
Amir Leshem, Uri Erez
It is shown that a receiver equipped with two antennas may null an arbitrary large number of spatial directions to any desired accuracy, while maintaining the interference-free sig…
Spectrum and Energy Efficient Multiple Access for Detection in Wireless Sensor Networks
Kobi Cohen, Amir Leshem
We consider a binary hypothesis testing problem using Wireless Sensor Networks (WSNs). The decision is made by a fusion center and is based on received data from the sensors. We fo…
Energy Efficiency of Opportunistic Device-to-Device Relaying Under Lognormal Shadowing
S. M. Zafaruddin, Jan Plachy, Zdenek Becvar +1
Energy consumption is a major limitation of low power and mobile devices. Efficient transmission protocols are required to minimize an energy consumption of the mobile devices for…
Asymptotically Optimal Resource Block Allocation With Limited Feedback
Ilai Bistritz, Amir Leshem
Consider a channel allocation problem over a frequency-selective channel.There are K channels (frequency bands) and N users such that K=bN for some positive integer b. We want to a…
Phase Noise Compensation for OFDM Systems
Amir Leshem, Michal Yemini
We describe a low complexity method for time domain compensation of phase noise in OFDM systems. We extend existing methods in several respects. First we suggest using the Karhunen…
