Abstract
A point-to-point (P2P) communication system based on the CPM-DSSS scheme ensures reliability, security, and antijamming capabilities. However, for reliable detection of data carrier synchronization of CPM-DSSS based system is one of the requirements. This paper presents a joint algorithm for carrier frequency offset (CFO) and carrier phase offset (CPO) estimation for CPM-DSSS based P2P system. The results indicate that the proposed CFO estimator is unbiased and can accurately estimate a wide range of offsets. Moreover, the proposed algorithm is compared with another research work. The results show that the proposed CFO and CPO estimation algorithm outperforms its counterpart with a performance improvement of about 9 dB and above, respectively. The effectiveness of the proposed estimator in the Stanford University Interim (SUI)-1 multipath fading channel is also demonstrated. Finally, the proposed estimator?s bit-error-rate (BER) performance and computational complexity are also given for the CPM-DSSS P2P system.
