    摘要： In a subband echo cancellation for a multichannel teleconference, received signals x1(k), x2(k), . . . , xI(k) of each channel are divided into N subband signals, an echo y(k) picked up by a microphone 16j after propagation over an echo path is divided into N subband signals y0(k), . . . ,yN−1(k), and vectors each composed of a time sequence of subband received signals x1(k), . . . , xI(k) are combined for each corresponding subband. The combined vector and an echo cancellation error signal in the corresponding subband are input into an estimation part 19n, wherein a cross-correlation variation component is extracted. The extracted component is used as an adjustment vector to iteratively adjust the impulse response of an estimated echo path. The combined vector is applied to an estimated echo path 18n formed by the adjusted value to obtain an echo replica. An echo cancellation error signal en(k) is calculated from the echo replica and a subband echo yn(k).

    摘要： A remote monitoring system for instrumentation that is capable of measuring certain characteristics of a process such as a pH value includes an instrument for providing a measurement output signal which can be stored. A comparison circuit can compare the output signal with a predetermined value. A transmitter can transmit when the output signal exceeds the predetermined value, and a receiver can receive the output signal and convert it into a measured result. The instrumentation can be pulled from the receiver and the output signals can be encoded to identify a particular instrument with distinct transmission time periods available in a plurality of transmitting channels.
