Abstract

An improved quadratic interpolation method to process correlation curve data was proposed to improve precision of DSSS PN code phase measurement. The method chose several data points around correlation curve peak by a correlator spacing d, and chose three which had maximum correlation value to determine a quadratic interpolation function, then located the maximum point of the function to obtain the precise PN code phase offset. Simulation showed that the improved method can effectively improve the PN code phase measurement precision and the measurement range.
