Abstract: A path creation support apparatus acquires either a portion of the parameters required for path creation or parameter decision information for deciding this portion of the parameters from a storage system or a host. The path creation support apparatus decides the portion of the parameters based on the parameter decision information. Upon receiving an access path creation start request, the path creation support apparatus sends an access path creation indication to the host and the storage system which specifies the parameters together with the access path creation start request, and either the parameters acquired beforehand or the acquired parameters decided based on the parameter decision information.

Abstract: Echo-canceling apparatus of the invention includes transfer function estimation unit which estimates a transfer function corresponding to the reverberation of a room attached to a voice after it is output from a loudspeaker and before it is input to a microphone, a first filter unit which operates using the transfer function, a first subtraction unit which subtracts the output signal of the first filter unit from the signal from the microphone, a second filter unit which operates using the transfer function copied from the first filter unit in case the estimation accuracy of the transfer function estimation unit is high, a second subtraction unit which subtracts the output signal of the second filter unit from the signal from the microphone, a singing detection unit which detects singing, a notch filter unit which notches a specific frequency band component in the signal received from a far-end speaker, and a switch unit which selects between the signal from the far-end speaker processed by the notch filter u

Abstract: A signal separation apparatus is capable of extracting original signals of two different systems with a high quality from received signals containing the original signals superposed each other in the course of transmission. In signal transmission from senders to receiver equipment, the signals to be sent separately are susceptible to mutual interference and superposition with given amplification factors in the course of transmission through respective transmission channels to such an extent that these signals can no more be discerned from each other by a receiver.
