Efficient Redundant Assignments under Fault-Tolerance Constraints
We consider the problem of computing minimum congestion, fault-tolerant, redundant assignments of messages to faulty parallel delivery channels. In particular, we are given a set M of faulty channels, each having an integer capacity ci and failing independently with probability fi. We are also given a set of messages to be delivered over M, and a fault-tolerance constraint (1 ?), and we seek a ...
متن کاملImproved Turbo Decoding through Belief Propagation
Absfract-It has long been recognized that graphical representations of parallel concatenated codes contain loops. These loops make it extremely difficult to use the standard, probabilistic methods for graphs to obtain any insight as to the functionality of turbo decoding. Graphbased techniques do, however, lead to useful extensions and generalizations of the turbo decoding concept. In this pape...
متن کاملComdined Turbo Block Decoding and Equalisation
In this paper, the combination of equalization and turbo decoding is studied. In the iterative decoding of a product code in block turbo coding system, the equalization process is performed within the iteration loop. The present study aims to investigate the decision feedback equalizer (DFE) incorporated in the iterative decoding. Simulation results show that the more severe the channel interfe...

متن کاملTurbo equalization: adaptive equalization and channel decoding jointly optimized
This paper deals with a receiver scheme where adaptive equalization and channel decoding are jointly optimized in an iterative process. This receiver scheme is well suited for transmissions over a frequency-selective channel with large delay spread and for high spectral efficiency modulations. A low-complexity soft-input soft-output -ary channel decoder is proposed. Turbo equalization allows in...
