中文摘要 | A direct demodulation method was developed for binary offset carrier (BOC) modulated satellite navigation signals with unknown structures. The method uses the demodulation algorithm for binary phase shift keying (BPSK) signals to synchronize the spread spectrum code and remove the carrier. The subcarrier of the BOC modulated signal is then also removed. This method was implemented in a field programmable gate array (FPGA) for demodulation experiment which shows that this method provides robust demodulation of BOC modulated signals with a bit error ratio below 1 * 10/sup -5/ if the SNR (E/sub b//N/sub 0/) is higher than 11 dB. |
