Abstract:
1. A correlation processor provided for a receiver that receives a signal having a predetermined center frequency and a specific wave form with a finite time duration, for carrying out a correlation process on the received signal, comprising: a filter coefficient unit configured to calculate a coefficient vector that zeroes sample values of all sample points except a peak center sample point of a main lobe of a correlation-processed waveform of the received signal and sample points on each side of the peak center and minimizes S/N loss of the sample value of the peak center sample point of the main lobe; and a filter configured to carry out a correlation process on the received signal according to the coefficient vector calculated by the filter coefficient unit, wherein the filter coefficient unit provides a coefficient vector {right arrow over (H)} here, N x is a number of non-zero output points in the vicinity of a peak, N f is the number of points in each column and row of every matrix, T is a transposed matrix, asterisk “*” is a complex conjugate, and α is an optional complex constant.
