On the effect of SNR and superdirective beamforming in speaker diarisation in meetings [PDF]
This paper examines the effect of sensor performance on speaker diarisation in meetings and investigates the use of more advanced beamforming techniques, beyond the typically employed delay-sum beamformer, for mitigating the effects of poorer sensor ...

A Two-Stage Method for Short-Wave Target Localization Using DOA and TDOA Measurements
The ionosphere can make the short-wave source localization problem further non-linear, leading to a complicated solution process. This paper proposed a coordinated positioning algorithm based on the ionospheric virtual height (IVH) model to jointly ...
