20090079635 | METHOD AND APPARATUS FOR ADAPTIVE DIRECTION ESTIMATION OF RADIO WAVES - In an environment of temporally and spatially uncorrelated white additive noise, the direction estimation apparatus for coherent signals calculates (M−1) instantaneous cross-correlations between some array data, and selecting multiple pairs each of which is consisted of p instantaneous correlations from the (M−1) instantaneous cross-correlations to form a Hankel correlation matrix. Next, the apparatus divides that Hankel matrix into an upper submatrix and a lower submatrix and then calculates a linear operator at time n by using the adaptive LMS algorithm with a fixed or time-varying step-size parameter and or using the adaptive NLMS algorithm from the two submatrices. Then a noise subspace is estimated from that linear operator. Finally the directions of incident signals at time n is estimated and tracked by using that noise subspace with Newton approximation. | 03-26-2009 |

20130250817 | METHOD OF PASSING SIGNAL EVENTS THROUGH A VOICE OVER IP AUDIO MIXER DEVICE - In Voice-over-IP or like systems, audio mixers are used for implanting conferencing applications for IP networks. In such systems, a problem exists as how to pass through user signal events, such a DTMF digits, in-band as well as out-of-band telephony events (RFC 2833/4733) because they are not handled well in such systems. In accordance with certain embodiments, a signalling event in incoming audio packets or user signalling event received out-of-band is detected at one of the inputs. A meta-data representation of the signal event is attached to the audio and passed through the mixer for regeneration, as in-band or out-of-band telephony events, on the other side of the mixer. | 09-26-2013 |
