A Fast Acquisition Algorithm with DBZP Truncation Correlation for the Long Code Signal

doi:10.3969/j.issn.1000-1093.2019.03.012

Abstract

Abstract: The acquisition speed and efficiency of military communication signal are limited as a result of using long-periodic pseudo noise code. A fast acquisition algorithm with double block zero padding (DBZP) truncation correlation for the long code signal is proposed. In the proposed algorithm, the spectral asymmetry of complex sequences is applied to the truncation pretreatment, and the block correlations are executed using DBZP and the circular shifting for less computational complexity and increased acquisition speed. The energy compensation technique is adopted to improve environment adaptability, which makes the algorithm effectively process two-dimensional fast acquisition. The simulated results show that the proposed algorithm has better performance in acquisition speed and environment adaptability compared to the traditional acquisition algorithms in time domain. Key

Key words: long-periodicpseudonoisecode, acquisition, truncationcorrelation, doubleblockzeropadding, energycompensation
