Abstracts

A phase-coherent direct sequence (DS) and frequency hopping (FH) spread-spectrum signal has a much wider bandwidth than simple DS spread spectrum signals. Due to the non-linearity of ionosphere and frequency hopping scheme of the signal, the binary phase shift keying (BPSK) bit error rate (BER) deteriorates. Under the assumption of purely-background ionosphere dispersion and a uniformly-distributed FH pattern, the BERs of both the pilot signal and the long-term signal in a specific DS/FH satellite link are acquired through using the mathematical tools concerning the probability density functions of random variables (RVs). Simulations under constant ionosphere dispersion and uniformly-distributed FH pattern scintillation conditions are carried out to verify the results of BERs.
