Acquisition Algorithm Combining Parallel Code Phase with FractalReconstruction of TMBOC Modulation Signal

Abstract

Abstract: Abstract： Aimed at the ambiguity in acquisition of the TMBOC modulation signal caused by the multipeaks of autocorrelation function, this paper proposed an acquisition algorithm combining parallel code phase with fractalreconstruction to remove ambiguity. The algorithm demodulates the received signal, and uses local PN code and BOC code to correlate with demodulated signal. Next, it takes the absolute value of the results and addition. Finally, it utilizes the fractalreconstruction algorithm to fold a new correlation function without subpeaks. Theoretical analysis and simulation results show that the algorithm can capture the signal effectively with low complexity. Moreover, its correlation peak increases by 43.7% compared to the ASPeCT algorithm, and its main peak power reaches 96% through twopath channel.
