On the Relationship Between Measures of Relative Efficiency for Random Signal Detection
Nagananda, K. G
Relative efficiency (RE), the Pitman asymptotic relative efficiency (ARE) and efficacy are important relative performance measures of signal detection techniques. These measures al…
Secure Communication in Dynamic Wireless Ad hoc Networks
B. N. Bharath, K. G. Nagananda
We consider a wireless ad hoc network in the presence of eavesdroppers (EDs), where the nodes are distributed according to independent Poisson point processes (PPPs). The legitimat…
Reduced-rank Analysis of the Total Least Squares
K. G. Nagananda, Pramod Khargonekar
The reduced-rank method exploits the distortion-variance tradeoff to yield superior solutions for classic problems in statistical signal processing such as parameter estimation and…
Tight Bounds on the Weighted Sum of MMSEs with Applications in Distributed Estimation
Michael Fauß, Abdelhak M. Zoubir, Alex Dytso +2
In this paper, tight upper and lower bounds are derived on the weighted sum of minimum mean-squared errors for additive Gaussian noise channels. The bounds are obtained by constrai…
Energy-efficient Decision Fusion for Distributed Detection in Wireless Sensor Networks
N. Sriranga, K. G. Nagananda, R. S. Blum +2
This paper proposes an energy-efficient counting rule for distributed detection by ordering sensor transmissions in wireless sensor networks. In the counting rule-based detection i…
Caching With Time-Varying Popularity Profiles: A Learning-Theoretic Perspective
B. N. Bharath, K. G. Nagananda, D. Gündüz +1
Content caching at the small-cell base stations (sBSs) in a heterogeneous wireless network is considered. A cost function is proposed that captures the backhaul link load called th…
