Abstract :
This paper studies the performance of a hybrid DS-SFH signal in the presence of partial band multitone jamming and AWGN. MSK is employed as FH spread spectrum modulation. The DS spread signal bandwidth is equal to the FH slot spacing. An equation for the BER is developed. Performance is evaluated, assuming a worst case jammer strategy. The analysis is performed for various system parameters such as a DS-SFH hybrid ratio, the number of jamming tones, SNR, and JSR. It is shown that, in some cases, the addition of DS spreading to an FH system, without increasing the total system bandwidth, can significantly improve the system´s resistance to partial band multitone jamming
