    摘要: The conventional combination cannot realize an efficient road traffic system as a whole. A transmission system has a plurality of modules installed at different positions along a predetermined road. Each of the plurality of the modules includes a receiving section for receiving an input signal and a transmission section for transmitting an output signal on the basis of the input signal according to a predetermined radio scheme. Each of the plurality of the modules receives and transmits a signal, whereby the whole or part of the information contained in the signal is transmitted along the whole or part of the predetermined road. This transmission system can construct an efficient integrated road traffic system as a whole.

    摘要: A noise signal prediction system includes a signal detector for receiving a mixed signal having a voice signal and a background noise signal and for detecting the presence and absence of the voice signal contained in the mixed signal. A noise level detector is provided for detecting an actual noise level at each sampling cycle during the absence of the voice signal. A storing circuit stores the noise levels for a predetermined number of past sampling cycles. A predicting circuit predicts a noise level of a next sampling cycle based on the stored noise levels in the storing circuit. The storing circuit receiving and stores the actual noise levels during the absence of the voice signal, but stores the predicted noise levels during the presence of the voice signal.

    摘要: A signal processing unit separates voice signals and non-voice audio signals contained in a mixed audio signal. The mixed audio signal is channel divided, and the voice signal portions of the channel divided mixed audio signal are detected and extracted at one output. Non-voice audio signals contained in the voice signal portions are predicted based on the non-voice audio signal portions of the mixed audio signal. The thus predicted non-voice audio signals are combined with extracted non-voice audio signals to obtain continuous non-voice audio signals which are output at a second output. Alternately, instead of extracting the voice signals from the mixed audio signal, the predicted non-voice signals are removed from the mixed audio signal to obtain the voice signals which are output on the first output.
