摘要

高效、可靠的信息传播是移动WiMAX (IEEE 802.16e)等下一代无线通信网络所要求的关键品质。为此，标准的物理层配备了几种调制和前向纠错编码方案。本文研究了IEEE 802.16e-2005物理层中使用不同比率的低密度奇偶校验(LDPC)码类作为预码的Raptor码的性能。结果表明，在加性高斯白噪声(AWGN)信道下，Raptor码的性能优于LPDC码。

Performance analysis of raptor code-based IEEE 802.16e system with different modulations techniques

Efficient and reliable dissemination of information are critical qualities required from the next-generation wireless communications networks such as mobile WiMAX (IEEE 802.16e). To this end, the physical layer of the standard is equipped with several modulations and forward error correction coding schemes. This paper investigated the performance of Raptor codes in IEEE 802.16e-2005 physical layer employing the different rates of Low Density Parity-Check (LDPC) code classes described in the standard as pre-codes. The results obtained showed that the performance of Raptor codes is better compared to the LPDC codes over the Additive White Gaussian Noise (AWGN) channel.
