Abstract
A correlation processor for a receiver is capable of carrying out a correlation process with highly suppressed side lobes, improved resolution, and minimized S/N loss. The correlation processor is provided for a receiver that receives a signal having a specific time width and shape, for carrying out a correlation process on the received signal. The correlation processor has a filter coefficient unit 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 to carry out a correlation process on the received signal according to the coefficient vector calculated by the filter coefficient unit.
