Abstract Joint tactical information distribution system (JTIDS) is a kind of widely used situational awareness data-link. To solve the performance deterioration problem of the rate-enhanced JTIDS in the presence of partial-band barrage jamming, a low complexity method for interference detection and erasure is proposed. First of all, the signal-to-noise ratio (SNR) of each pulse is estimated and the pulse is classified roughly. Then, the average SNR of all the normal pulses in the time slot is estimated. Finally, a fine pulse classification is performed, and each pulse is given an erasure-factor in a certain strategy. Simulation shows that this method greatly eases the effects of the partial-band barrage jamming on the reception performance and significantly reduces the bit error rate. The method is low complexity and easy to implement.
