| 摘 要： | 以分组码为子码构成的分组Turbo码(BTC),相比传统卷积Turbo码具有收敛速度快等优点。研究了分组Turbo码的译码算法及其简化修正算法,并对它们在802.16a多载波OFDM系统中做了性能仿真和分析。验证了分组Turbo码可以在较少的迭代次数达到较好的性能,简化修正算法可以大大降低算法复杂度,且性能损失不大。

| Abstract: | Block Turbo codes(BTC) whose subcodes are block codes have many advantages comparing with convolution Turbo codes, such as quick convergence speed,etc. In this paper, the decoding algorithm of BTC is modified and simplified, and the emulation about BTC is made in 802.16a OFDM systems.The results prove that BTC performs well in reducing iteratives, and by simplification and modification,the algorithm may be made much simpler with no losses to some extent. |
