Performance Analysis of 3-dimensional Turbo Codes
Turbo codes have gained considerable attention since their introduction by Berrou and al. in 1993 due to their near capacity performance and low decoding complexity. The conventional turbo code is a parallel concatenation of two identical recursive systematic convolutional encoders separated by a pseudo-random interleaver. In this work, we propose a modified three Dimensional Turbo Code (3D-TCs...

متن کاملPerformance Analysis of 3-Dimensional Turbo Codes
In this work, we consider the minimum distance properties and convergence thresholds of 3-dimensional turbo codes (3D-TCs), recently introduced by Berrou et al.. Here, we consider binary 3D-TCs while the original work of Berrou et al. considered double-binary codes. In the first part of the paper, the minimum distance properties are analyzed from an ensemble perspective, both in the finite-leng...
متن کاملPerformance Analysis of Multilevel Punctured Turbo Codes
In applications of wireless packet-oriented video and image communications, a special coding scheme, referred to as multilevel coding (MLC), exhibits both power and bandwidth efficiency by jointly optimizing channel coding and modulation. In particular, MLC is suitable for communications over a degraded broadcast channel due to its superposition structure. Moreover, the hierarchical channel cod...
