چکیده
In this paper, we presents the performance measure of the wireless Orthogonal Frequency Division Multiplexing (OFDM) system based on Raptor codes. Different coding techniques are used for the performance evaluation such as convolution code; turbo codes, RS codes and Low density parity check (LDPC) codes. We are using the Raptor codes to evaluate the performance of the wireless OFDM system. Raptor code is new emerging rateless code which has shown amazing performance over variety of channels. Different channel model are used for the performance measure. We use the Stanford University Interim (SUI-3) channel models. Two performance measure parameters are bit error rate and spectral efficiency. Simulation results are presented for the effectiveness of the proposed Raptor codes with Stanford University Interim (SUI3) channel. The simulation result based on 16-QAM and 64QAM modulation technique using Raptor codes for BER and spectral efficiency measure. Result also reveals that the performance improves with different modulation techniques.

Orthogonal Frequency Division Multiplexing (OFDM) is of the strong prospects as a future wireless communication system. Improved spectral efficiency has been found in OFDM based on DFT, has a good orthogonality but inter symbol interference (ISI) and inter carrier interference (ICI) degrade the performance. ISI and ICI can be improved by using cyclic prefix (CP). About 20% of bandwidth is consu...
