Detection of Signals in Colored Noise: Leading Eigenvalue Test for Non-central $F$-matrices

no code implementations30 Jan 2024 Prathapasinghe Dharmawansa, Saman Atapattu, Jamie Evans, Kandeepan Sithamparanathan

In particular, we focus on detecting an unknown non-random signal by capitalizing on the leading eigenvalue of the whitened sample covariance matrix as the test statistic (a. k. a.

$F$-matrix) which is constructed by whitening the signal bearing sample covariance matrix with noise-only sample covariance matrix.

Flex-Net: A Graph Neural Network Approach to Resource Management in Flexible Duplex Networks

1 code implementation20 Jan 2023 Tharaka Perera, Saman Atapattu, Yuting Fang, Prathapasinghe Dharmawansa, Jamie Evans

Flexible duplex networks allow users to dynamically employ uplink and downlink channels without static time scheduling, thereby utilizing the network resources efficiently.
