A self-steering digital microphone array
[Proceedings] ICASSP 91: 1991 International Conference on Acoustics, Speech, and Signal Processing, 1991A self-steering microphone array for teleconferencing in which the digitally implemented steering algorithm consists of two parts is presented. The first part, the beamforming, is based on known concepts. The second part, a novel voting algorithm, integrates elements of pattern classification and exploits temporal characteristics of speech signals.

Differential Microphone Arrays
2006Noise and reverberation can seriously degrade both microphone reception and loudspeaker transmission of audio signals in telecommunication systems. Directional loudspeakers and microphone arrays can be effective in combating these problems. This chapter covers the design and implementation of differential arrays that are by definition small compared to
