The Design and Implementation of a Processor for Code Acquisition Based on Circular Correlation

Abstract

The advantage of circular correlation based on FFT is getting a large searching range ¿less time for processing and making the speed of acquisition much faster. The parameters such as the data points¿segments and the ratio of sampling all effect the capability of the acquisition in the process of the circular correlation. The key parameters of the process based on FPGA can be designed and optimized in order to further research the capability of circular correlation.
