An E cient Software Implementationof a Forward Error
نویسنده
چکیده
Today, Forward Error-Correcting (FEC) codes are mainly implemented in hardware, and many believe that their complexity prohibit their software implementation. This paper presents in detail how the performances of a software implementantion can be signiicantly improved. Diierent levels of optimization which are independent of the working environment are presented and discussed. The coding through-put of 100 Mbps on an UltraSparc 1 shows that FEC codes can be easily added to multimedia applications without requiring dedicated hardware support. As a case study, we use FEC codes to protect AAL5-PDUs from cell losses in ATM networks.

متن کامل2D DC resistivity forward modeling based on the integral equation method and a comparison with the RES2DMOD results
A 2D forward modeling code for DC resistivity is developed based on the integral equation (IE) method. Here, a linear relation between model parameters and apparent resistivity values is proposed, although the resistivity modeling is generally a nonlinear problem. Two synthetic cases are considered for the numerical calculations and the results derived from IE code are compared with the RES2DMO...
متن کاملJoint Allocation of Bandwidth and FEC Across Layers for Video Multicast over Wired and Wireless Networks
Layered multicast is an e cient technique to deliver video to users over wired and wireless networks. In this paper, we consider such a multicast system in which the server adapts the bandwidth and FEC of each layer so as to maximize overall video quality, given the heterogeneous user characteristics in terms of their end-to-end bandwidth, packet drop rate over the wired network, and bit error ...
