An Analytical Model for Optimum Byte-Level and Packet-Level FEC Assignment Using Buffer Dynamics
Analytical Model Optimum Byte-Level Packet-Level FEC Assignment Buffer Dynamics
2009/9/4
This letter presents an analytical model that jointly exploits the buffer dynamics of both the sending and receiving nodes to find the optimum number of byte-level and packet-level forward error corre...
Low-MAC FEC controller for JPEG2000 image transmission over IEEE 802.15.4
FEC IEEE 802.15.4 JPEG2000 low-MAC
2010/2/2
In this paper, we propose the low-MAC FEC controller
for practical implementation of JPEG2000 image transmission using
IEEE 802.15.4. The proposed low-MAC FEC controller has very
small HW size and ...
采用自适应FEC的卫星ATM网络的有效带宽估计
卫星ATM 自适应FEC 接纳控制
2009/5/8
该文针对采用自适应FEC(AFEC)的卫星ATM网络，研究了两种用于接纳控制的有效带宽估计方法，由于AFEC码率的动态特性使业务实际的传输速率具有不固定性，因此估计有效带宽时要考虑AFEC的影响，作者首先针对一般卫星时变信道和多码率AFEC情况下的卫星ATM，应用流体近似方法分析了有效带宽的计算，然而该方法要求的条件及计算复杂度均比较高，应用中有局限性。以此方法为基础，作者又提出了采用修正因子的估...

分组级FEC 卫星通信 数据分发
2008/6/2
本文根据所给出的信道差错模型和里德所罗门删除码(RSE)编码技术，研究了在卫星数据分发系统中采用分组级前向纠错(FEC)技术的文件成功分发概率和吞吐量效率与文件长度、分组长度、接收站点数及RSE码纠错能力之间的关系，所得到的结论对于卫星数据分发系统中的参数选择及性能优化具有指导意义。
FEC-based Multiple Description Coding for Heterogeneous Client Bandwidths
FEC-based Multiple Description Coding Heterogeneous Client Bandwidths
2010/12/14
We consider applying the FEC-based multiple description coding method for multicasting a source to a
set of clients with heterogeneous access bandwidths. In the scenario where different clients acce...
Quality Smoothing for FEC-based Multiple Description Coding
Quality Smoothing FEC-based Multiple Description Coding
2010/12/14
When sending a scalable video sequence over packet loss channels, one usually partitions it into groups of frames
(GOFs), and protects each GOF using the FEC based multiple description coding (FEC-MD...
