摘要:
由于误比特率分布更能深刻细致地描述纠错码的纠镨能力,因此,采用误比特率分布的方法,对Turbo码中3GPP交织器、分组交织器和随机交织器在不同码率下的性能进行了比较和分析.仿真结果显示,分组交织器的误比特率分布具有明显的周期特征;随机交织器的误比特率分布的随机特性更为明显,误码率分布比分组交织器分布的更为广泛;而对于3gpp交织器,它的误比特率分布具有较为平坦的分布曲线和较低的平均误比特率.
Abstract:
The ber distributions，which can give a detailed description about the error correcting ability of e卜ror control codes，are introduced in this paper to analyze the interleavers of 3 GPP interleaver．block interlea—ver and random interleaver．The ber distributions are given under different puncturing patterns．The resultsshow that the ber distribution of block interleaver is periodic apparently and that of the random interleaver isspread more randomly．As for the 3 GPP interleaver，because of its combination construction，its bet distribu．tion has the advantages of both block and random interleavers。i.e.it has more flat distribution and lower av-eraged ber．
