Detection of Single vs Multiple Antenna Transmission Systems Using Pilot Data
Thakshila Wimalajeewa, Pramod K Varshney, Wei Su
In this paper, we consider the problem of classifying the transmission system when it is not known a priori whether the transmission is via a single antenna or multiple antennas. T…
Detection with Multimodal Dependent Data Using Low Dimensional Random Projections
Thakshila Wimalajeewa, Pramod K. Varshney
Performing likelihood ratio based detection with high dimensional multimodal data is a challenging problem since the computation of the joint probability density functions (pdfs) i…
Asynchronous Linear Modulation Classification with Multiple Sensors via Generalized EM Algorithm
O. Ozdemir, T. Wimalajeewa, B. Dulek +2
In this paper, we consider the problem of automatic modulation classification with multiple sensors in the presence of unknown time offset, phase offset and received signal amplitu…
Decentralized Subspace Pursuit for Joint Sparsity Pattern Recovery
Gang Li, Thakshila Wimalajeewa, Pramod K. Varshney
To solve the problem of joint sparsity pattern recovery in a decen-tralized network, we propose an algorithm named decentralized and collaborative subspace pursuit (DCSP). The basi…
