Abstract

In order to facilitate efficient and reliable delivery of information, the physical layer of mobile WiMAX (IEEE 802.16e-2005) is equipped with several forward error correction coding schemes. In this paper, we investigate the performance of raptor codes in the IEEE 802.16e-2005 physical layer employing the different rates 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.
