Abstract :
TDDM-BOC modulation signal is realized to overlap with different signals in the same frequency and has the better anti-jamming ability, because of the unique character of split spectrum and auto-correlation multi-peak. According to the auto-correlation character of TDDM-BOC modulation signal, an algorithm is proposed for direct acquiring TDDM-BOC signal based on sub-sampling. With decreasing Signal-to-Noise, the algorithm is simulated and its performance is analyzed. The validity of the algorithm with the lower SNR is proved by simulation result under band-pass sub-sampling. The number of computing data is much less, because of the lower sampling frequency.
