摘要
plurality of signal sources from the signal received through the antenna array to the receiver in the signal arrival direction of each (DOA) The present invention relates to spatially smoothed magnetic convolution-based method of predicting the arrival direction for each prediction, (a) comprising a complex yen the antenna received signals by applying the envelope (Complex envelope) expressed by a linear expression vector; (B) to obtain a new signal by performing convolution operation automatically (auto convolution) in the received signal; (C) converting the first signal into data in frequency domain through a Fourier transform to (the signal vector), the image of a linear vector; And (d) representing the frequency domain through a Fourier transform to the new signal vector; (E) extracting a first spectral density matrix by an operator to perform a multiplication of a matrix element for the elements between the two (the delta red); And, (f) spatially smoothing the spectral density of the first matrix to provide a configuration including a step of obtaining the second spectral density matrix. By the respective prediction methods, such as the direction of signal arrival, the care Any number of noise signals arriving at the antenna array are correlated and have the added noise in the environment of the area at any angle of signal arrival directions (DOA) and can be effectively predicted. ;
