Future GNSS signal using BOC modulation brings the advantages of positioning accuracy and multipath rejection. However, the BOC signal has an ambiguous autocorrelation function that complicates the process of acquisition. Three techniques that solve the ambiguous problem are BPSK-like, Sub Carrier Phase Cancellation, and Bump Jumping. In this paper, these methods are implemented by means of a DSP/FPGA board. Moreover, an experiment is conducted to examine and compare the performance of these techniques.
