Optimization of Fec in Ieee 802.16d
نویسنده
چکیده
WiMAX based on IEEE Std. 802.16 carries high data rates and large coverage to wireless networks. It provide high speed wireless broadband connectivity building the gap between 3G and Wireless LAN (WLAN).The main focus of this paper is on 802.16d OFDM PHY layer. The simulation will compare the performance of SF and STF – OFDM over different SUI channel models. Forward error correction is used to improve the reliability of transmitted data. The main categories of FEC are block and convolutional codes. In the simulation block and convolutional codes are frequently combined in concatenated coding schemes in which the convolutional codes does most of the work and the block code “mops up” any errors made by the convolutional decoder.

متن کاملFPGA Implementation of FFT Algorithm for OFDM Based IEEE 802.16d (Fixed WiMAX) Communications
⎯The IEEE 802.16d communication standard uses orthogonal frequency division multiplexing (OFDM). In the widely used OFDM systems, the fast Fourier transform (FFT) and inverse fast Fourier transform pairs are used to modulate and demodulate the data constellation on the sub-carriers. In this paper, a high level implementation of a high performance FFT for OFDM modulator and demodulator is presen...
متن کاملJoint source/FEC rate selection for quality-optimal MPEG-2 video delivery
This paper deals with the optimal allocation of MPEG-2 encoding and media-independent forward error correction (FEC) rates under a total given bandwidth. The optimality is defined in terms of minimum perceptual distortion given a set of video and network parameters. We first derive the set of equations leading to the residual loss process parameters. That is, the packet loss ratio (PLR) and the...
متن کاملAdaptive two-stage FEC scheme for scalable video transmission over wireless networks
In this paper, we propose a two-stage FEC scheme with an enhanced MAC protocol especially for multimedia data transmission over wireless LANs. The proposed scheme enables the joint optimization of protection strategies across the protocol stack, and packets with errors are delivered to the application layer for correction or drop. In stage 1, packet-level FEC is added across packets at the appl...
