摘要

Continuous Phase Modulation-Direct Sequence Spread Spectrum (CPM-DSSS) is a promising technique with the advantages of constant envelope, high spectral efficiency and anti-jamming. The demodulation of CPM-DSSS requires precise synchronisation of carrier phase and symbol timing offset at the receiver side. However, the existing synchronization methods have the problem of high computational complexity. In this work, a low-complexity joint estimator of carrier phase and symbol timing offset based on CPM-DSSS and PAM decomposition is proposed. By performing PAM decomposition on the CPM-DSSS signal and optimising the estimation algorithm with energy weights of each pulse, the computational complexity is reduced by 90 %. Simulation analysis shows that the proposed estimator can achieve the same estimation performance as the ML algorithm with low operational complexity.
