Abstract: This article proposes a full-metal omnidirectional series-fed filtenna array. The antenna is primarily composed of an outer metal shell, a built-in metal post and three pairs of open-circuit ...

This paper presents a generic beamformer design algorithm for arbitrary microphone array geometry. It makes efficient use of noise models for ambient and instrumental and microphone directivity ...

Abstract: It is difficult for a standing-wave waveguide slot array antenna to generate a complex beam shape in H-plane, such as the cosecant squared pattern. The reason is that a conventional standing ...

Speech separation has been shown effective for multi-talker speech recognition. Under the ad hoc microphone array setup where the array consists of spatially distributed asynchronous microphones, ...

Ukrainian forces say they have hit an oil terminal, a pipeline, two parked jet fighters, and two ships in a series of strikes on Russian soil KYIV, Ukraine -- Ukrainian forces hit an oil terminal, a ...
