A simplified analysis with Gaussian assumption of initial message is proposed in the worst case of interference, which has much lower complexity and provides a very close result to DDE. Based on this simplified analysis, the linear programming is employed to design rateless codes and the simulation results on partial-band interference channels show that the optimized codes have more powerful antijamming performance than the codes originally designed for conventional systems.<\/jats:p>","DOI":"10.1155\/2020\/9049284","type":"journal-article","created":{"date-parts":[[2020,2,10]],"date-time":"2020-02-10T18:32:31Z","timestamp":1581359551000},"page":"1-8","source":"Crossref","is-referenced-by-count":2,"title":["Analysis
