N2 - Aiming at the arrival sky-wave signal in radio positioning system operating in CDMA mode, a method for suppressing sky-wave signal is provided. The mathematie mode used for signal processing is established, and the possible solutions are provided. In the paper, a structure and the signal processing flow implemented the presented algorithm in the receiver are presented. A parallel multi-channels signal searching idea is adopted, some of which processes the sky-wave signal, and some of which processes the ground-wave signal. Based on the MLE theory, an algorithm for estimating the amplitude and the phase of arrival sky-wave signal is presented. Numerical analysis and simulation show that higher the estimation accuracy of the sky-wave signal parameter, rapider processing speed, and simpler implementation.
