Performance Analysis of Raptor Codes in Mobile WiMax Using FEC Scheme
The physical layer of mobile WiMAX (IEEE 802.1e-2005) is equipped with several Forward Error Correction (FEC) coding schemes, because to facilitate efficient and reliable delivery of information. Information may be any sequence of data or digital image. In this paper, the authors investigate the performance of raptor codes in the IEEE 802.16e-2005 physical layer for image transmission, employing different rate Low Density Parity Check (LDPC) code class described in the standard pre-codes. The simulation study is made with processing a black and white (monochrome) digital image under AWGN channel.
