• Satellite communication can be operated with various levels of on-board processing in order to transmit the signal effectively. In this paper, the BER performances of the bent pipe transponder (BPT), dehop only transponder (DOT) and dehop and rehop transponder (DRT) systems with FH-MFSK modulation are investigated in the presence of broad band interference, narrow band interference and tone-type interference, and compared each other for the dynamic ranges of data rates, spreading bandwidth and interference power. The numerical results show that DRT outperforms BPT and DOT, and DOT is less sensitive to uplink interference power under broad band interference environment than DRT. In the case of narrow band interference, the DRT system is more sensitive to ρ value, i.e., the ratio of the interference bandwidth to spreading bandwidth, than DOT. Among various interference types, further, it is observed that the performance of multi-tone interference in n = 1 band is the most pessimistic for all OBP techniques.
