Intra-pulse frequency coded (IPFC) signal, with its large time-bandwidth and low probability of interception characteristics, is widely applied to anti-jamming radar system. This paper focuses on the efficiency of interrupted sampling repeater jamming (ISRJ) under IPFC signal, and the influence on jamming effect with different signal forms and waveform parameters is mainly analyzed. The simulation results show that the ISRJ of step frequency coded signal and liner modulated frequency signal have similar jamming performance. The ISRJ of random frequency coded signal can only form a single false target at direct forwarding mode. Furthermore, with the increasing of the sub-pulse number, the ISRJ performance of random frequency coded signal will be reduced.

Filter-based publish/subscribe systems suffer from high subscription maintenance cost for each broker in the system
stores a large number of subscriptions. Advertisement and covering are not sufficient to conquer such problem. Thus,
subscription merging is proposed. However, current researches lack of an efficient and practical merging mechanism. In
this paper, we propose a novel subscription merging mechanism. The mechanism is both time and space efficient, and
can flexibly control the merging granularity. The merging mechanism has been verified through both theoretical and
simulation-based evaluation.
