The Performance Research of Vice Peak Restrained Acquisition Algorithm for MBOC Signal

With the development of the spread spectrum communication technology a new MBOC modulation technology has come into being. Its main autocorrelation peak is sharper than that of BOC signal, so it helps to improve the signal acquisition and tracking accuracy. But the multipeaks characteristics of its autocorrelation function, especially the vice peak characteristic, cause the ambiguous problems of acquisition processing. Thus, the acquisition technology research is carried out on this ambiguous problem from the perspective of vice peck inhibition. And give the best acquisition parameters analyzed for more effective of vice peak of autocorrelation function elimination method and BPSK - like algorithm. And then compare the performance among the vice peak of autocorrelation function elimination method, the whole band acquisition algorithm and BPSK - like algorithm from the perspective of vice peak restrain, main autocorrelation peak and acquisition time, thus, the effective and reasonable acquisition advices are given.
