【摘要】 本文对Turbo码中的关键部件——交织器作了分析,阐明了交织器在Turbo码中的重要作用。同时,混沌理论是非线性科学中的研究热点,对现代科学产生了广泛而深远的影响。本文基于Henon混沌模型和S-random交织器的设计思想提出了一种改进的交织器设计方法,并将其应用于Turbo码中。通过Turbo码的距离谱和联合界对比,本文设计的S-henon交织器在改善Turbo性能上优于S-random交织器。更多还原

【Abstract】 Interlever plays an important role in Turbo code theory. The selection of interleaver is the key to increase the correction performance. At the same time, Chaos theory as a focal topic of non-linear science have influenced on the development of modern science broadly and heavily. An improved method to design S-random interleaver based on Henon chaos model is presented. The designed S-henon interleaver is superior to the traditional S-random interleaver through the calculation of Turbo code’s distance spectrum and union bound respectively .更多还原
