On Secure Network Coding Over Networks With Unequal Link Capacities (2009)
Cui, Tao, Ho, Tracey, Kliewer, Joerg
This paper considers secure network coding over networks with unequal link capacities in the presence of a wiretapper that can wiretap any subset of k links. Existing results show that for the case...
Trapping Set Enumerators for Repeat Multiple Accumulate Code Ensembles (2009)
Koller, Christian, Amat, Alexandre Graell I, Kliewer, Joerg, Costello Jr, Daniel J.
The serial concatenation of a repetition code with two or more accumulators has the advantage of a simple encoder structure. Furthermore, the resulting ensemble is asymptotically good and exhibits...
Cui, Tao, Ho, Tracey, Kliewer, Joerg
We analyze the achievable rate in interference-free wireless networks with physical layer fading channels and orthogonal multiple access. As a starting point, the point-to-point channel is...
Coding Theorems for Repeat Multiple Accumulate Codes (2008)
Kliewer, Joerg, Zigangirov, Kamil S., Koller, Christian, Costello Jr, Daniel J.
In this paper the ensemble of codes formed by a serial concatenation of a repetition code with multiple accumulators connected through random interleavers is considered. Based on finite length weight...
