Abstract
A correlation pulse generator used in a receiver of a spread spectrum communication system comprises peak hold circuit for holding peak values of positive and negative correlation spikes, threshold setting circuits for generating thresholds based on the peak values, and a comparing circuit for comparing the threshold with a correlation spike to generate a correlation pulse, so that when a level difference exists between positive and negative correlation spike levels of a correlation output, their peaks can be held independently, and thresholds based on the peaks can be generated independently.
