A Space-Time Adaptive Processing Method Based on Sparse Reconstruction of Reverberation Interference
Xibei Gongye Daxue Xuebao, 2020 Aiming at the problem of how to obtain reverberation samples and estimate their covariance matrix in the space-time adaptive processing(STAP) of sonar system, a new space-time adaptive processing method is proposed based on sparse reconstruction of ...

Speech Dereverberation with a Reverberation Time Shortening Target
ICASSP 2023 - 2023 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2023 This work proposes a new learning target based on reverberation time shortening (RTS) for speech dereverberation. The learning target for dereverberation is usually set as the direct-path speech or optionally with some early reflections. This type of target suddenly truncates the reverberation, and thus it may not be suitable for network training.

Reverberation Time and Power Model in Indoor Wireless Scenarios [PDF]
Radioengineering, 2018 A novel, room-electromagnetics-theory-based model for reverberation time, path gain and Power Delay Profile (PDP) is proposed. Unlike the traditional models describing only the reflections, the new model takes not only reflections at boundaries, but also

TOPOLOGICAL REVERBERATIONS IN FLAT SPACE–TIMES [PDF]
International Journal of Modern Physics A, 2000 We study the role played by multiply-connectedness in the time evolution of the energy E(t) of a radiating system that lies in static flat space–time manifolds ℳ4 whose t= const spacelike sections ℳ3 are compact in at least one spatial direction.
