Study on Turbo Decoding Using Hard Decision Decoder -Principle of Hard-in Soft-out Decoding-

چکیده
We propose a new construction and decoding method for concatenated codes. One of the target coding schemes is a serially-concatenated coding scheme with a turbo code as the inner code and a Reed-Solomon (or other block) code as the outer code. The proposed decoding strategies include following two points. (1) New repetitive diagram of whole serial concatenated code is investigated. (2) To reduce complexity, hardinput soft-output decoding for the outer code is applied. Using a double error-correcting Reed-Solomon code as outer code, the results are evaluated and discussed.

Comdined 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 کاملBit-level soft-decision decoding of Reed-Solomon codes
HE practical importance of Reed-Solomon codes is well established (see [1]-[7]). The application of Reed-Solomon codes spans from deep-space communication standard [2] -[4] and over the air teletext broadcast [5] to frequency-hop spreadspectrum systems [6] and optical communication [7]. Harddecision decoders for RS codes are readily available using algebraic decoding algorithms. Such ...
متن کاملSoft-decision decoding offers a means of bridging the performance gap
Soft-decision decoding offers a means of bridging the performance gap between a block error-control system that uses hard-decision boundeddistance decoding, and one that uses maximum-likelihood decoding. Existing algorithms, however, tend to be complex in terms of hardware requirement. This paper presents a new class of soft-decision decoding algorithms, based on error-trapping decoding, which ...
