  Abstract

In this paper, we propose an unambiguous correlation function generation scheme for composite binary offset carrier (CBOC) signal tracking based on variable samplers. In the proposed scheme, we first obtain symmetric cross-correlation functions by sampling the autocorrelation function, where the variable sampler changes the position of the zero-crossing points of the cross-correlation functions, and adjusts the slope of the finally generated unambiguous correlation function. The proposed unambiguous correlation function is generated by weighted combinations of the cross-correlation and autocorrelation functions. In numerical results, it is confirmed that the proposed correlation function provides a better tracking error standard deviation (TESD) performance than those of the conventional ones.
