High deadline meeting rate of non-preemptive dynamic soft real time scheduling algorithm
(Institute of Electrical and Electronics Engineers (IEEE), 2012-11)
Hard real time systems were often implemented with preemptive scheduling, which gives priority to the highest priority task. In this paper we present a new non-preemptive scheduling of jobs meant for soft real time ...
Synthesis of finite length multi level sequences for clutter rejection in radar
(Institute of Electrical and Electronics Engineers (IEEE), 2012-07-24)
In radar systems the very low side-lobes that can be achieved with amplitude and phase modulated pulse trains make their use particularly attractive in systems requiring a large dynamic range. Moreover, the excellent ...
