Title: Method and apparatus for multi-channel acoustic echo cancellation
Inventor: SHIMAUCHI SUEHIRO
IPC: H04M9/08
Filed: 1996-09-25
Abstract: In a multi-channel acoustic echo cancellation, received signals in a plurality of channels are radiated as acoustic signals by a plurality of loudspeakers, received signal vectors in these channels are combined into a combined vector and a rearranged received signal vector in the case of at least two channels being exchanged is generated. By inputting the combined received signal vector into an echo replica generating part which simulates echo paths from the loudspeakers to at least one microphone, an echo replica is generated. The echo replica is subtracted from an echo output from the microphone to obtain a residual echo. Based on the relationship between the received signal vector and the corresponding residual echo and between the rearranged received signal vector and the corresponding approximated residual echo, an adjustment vector is obtained which is used to adjust the estimated echo path vector representing an impulse response of the echo replica generating part.

Abstract: Liquid polyamine crosslinking agent formulations based on trimerized toluylene 2,4- and/or 2,6-diisocyanate, with formation of an isocyanurate structure and hydrolysis of the isocyanate groups to amine groups, are described. The novel crosslinking agent formulations have a content of 40 to 80% of the total weight of the solids content of the crosslinking agent formulation of 1,3,5-tris-(3-amino-4-methyl-phenyl,2-methyl-3-aminophenyl) isocyanurate (I) which is not further condensed, and a content of not more than 1.0% of the total weight of the crosslinking agent formulations of toluylene-2,4- and/or -2,6-diamine (III). For the preparation, toluylene diisocyanate is trimerized, to form the isocyanurate structure, until 10 to 25% of the NCO groups have been reacted. The toluylene diisocyanate which has not undergone condensation is then distilled off, the bottom product formed by this operation is taken up directly in a solvent A and the 30 to 70% strength by weight solution formed by this procedure is metered into a hydrolysis in water/N,N-dialkyl-carboxylic acid amide in the presence of a catalytic amount of a basic catalyst. After the hydrolysis, the crosslinking agent formulations are brought to a solids content of 35 to 60% of the total weight ofthe formulation by distilling off a portion of the solvents and adding a solvent B.
