Joint Channel Impulse Response and Noise-Variance Estimation for OFDM/SDMA Systems Based on Expectation Maximization
Abstract—A joint channel impulse response (CIR) and noisevariance estimation scheme is proposed for multi-user MultipleInput-Multiple-Output (MIMO) Orthogonal Frequency-Division ...

Achievable Sum-Rate Analysis of Practical Multiuser Scheduling Schemes with Limited Feedback
— We study the performance of fair physical layer schedulers that select a pair of orthogonal users for simultaneous transmission. The schemes rely on partial channel state infor...

Security Vulnerabilities in Channel Assignment of Multi-Radio Multi-Channel Wireless Mesh Networks
— In order to fully exploit the aggregate bandwidth available in the radio spectrum, future Wireless Mesh Networks (WMN) are expected to take advantage of multiple orthogonal cha...

Green Codes: Energy-Efficient Short-Range Communication
Abstract-- A green code attempts to minimize the total energy per-bit required to communicate across a noisy channel. The classical information-theoretic approach neglects the ener...

Strong Secrecy and Reliable Byzantine Detection in the Presence of an Untrusted Relay
We consider a Gaussian two-hop network where the source and the destination can communicate only via a relay node who is both an eavesdropper and a Byzantine adversary. Both the s...
