摘要： PROBLEM TO BE SOLVED: To provide a receiver and a waveform processing method capable of suppressing the deterioration of signal quality after coupling and performing the coupling of signal waveform in a more natural state even when there is no separated signal waveform of coupling candidate, when successively coupling separated signal waveforms after blind separation processing and extracting the coupled signal waveforms as an original signal. SOLUTION: The separated signal waveforms obtained by the blind separation processing of a signal in which a plurality of original signals are mixed are successively coupled while using a designated signal direction as a key. Therein, when there is one wave that satisfies such separated signal waveforms that the designated signal direction is set to be the incoming direction, the separated signal waveforms are successively coupled and, when there are a plurality of waves or no wave that satisfy such separated signal waveforms that the designated signal direction is set to be the incoming direction, the separated signal waveforms are coupled to a destination of coupling that has the most significant correlation between the separated signal waveforms up to the just preceding one and the destination of coupling. Further, when there is no accordance of signal direction and no significant correlation, it is decided that the separation signal waveforms to be coupled are not obtained and the processed signal waveforms obtained by waveform extracting processing based on direction designation using the designated signal direction as a target are interpolated and coupled concerning the designated signal direction.

摘要： PROBLEM TO BE SOLVED: To receive a desired wave in an optimal state by improving a signal-to-noise ratio even when signal intensity is low and interference occurs. SOLUTION: Observation signals by two or more sensors 1-1 to 1-n are sampled by a sampling section 10 and supplied respectively to a beam formation section 22 and an interference wave suppressing section 23. A beam formation section 22 outputs waveform data using an algorithm such as a DBF. The interference wave suppressing section 23 outputs waveform data using an adaptive NUL formation algorithm etc. The pieces of waveform data are input respectively to equivalent signal-to-noise ratio operation sections 31 and 32. The equivalent signal-to-noise ratio operation sections 31 and 32 operate equivalent signal-to-noise ratios respectively based on the pieces of waveform data. By comparing the respective equivalent signal-to-noise ratios operated, either output signal from the beam formation section 22 and the interference wave suppressing section 23 is selected to be output as a received signal.

摘要： PROBLEM TO BE SOLVED: To provide a receiver which can perform predetermined signal processing only based on an effective observation signal to improve processing speed and accuracy of the processing results. SOLUTION: A number-of-signal estimating and processing part 20 generates a first covariance matrix from time series data of the observation signal and the number of data by a first eigen value analyzing part 22. The first covariance matrix is analyzed with the eigen value to obtain a first eigen value. A second eigen value analyzing part 23 generates a second covariance matrix from time series data and the number of data of a noise jamming signal without the observation signal. The second covariance matrix is analyzed with the eigen value to obtain a second eigen value. The difference between the first and the second eigen values is obtained by a subtractor 24. A number-of-signal determination part 25 outputs selection permit signals by the number of the difference larger than the reference value. A target signal selection part 26 selects the observation signals by the number of the signals according to the selection permit signals. COPYRIGHT: (C)2004,JPO
