Estimation of the direct-to-reverberant Energy Ratio using a spherical microphone array
Hanchi Chen, Prasanga N. Samarasinghe, Thushara D. Abhayapala +1
This paper proposes a practical approach to estimate the direct-to-reverberant energy ratio (DRR) using a spherical microphone array without having knowledge of the source signal.…
Achieving secrecy without knowing the number of eavesdropper antennas
Biao He, Xiangyun Zhou, Thushara D. Abhayapala
The existing research on physical layer security commonly assumes the number of eavesdropper antennas to be known. Although this assumption allows one to easily compute the achieva…
An Efficient Parameterization of the Room Transfer Function
Prasanga Samarasinghe, Thushara Abhayapala, Mark Poletti +1
This paper proposes an efficient parameterization of the Room Transfer Function (RTF). Typically, the RTF rapidly varies with varying source and receiver positions, hence requires…
