Ashenden, ISBN:Morgan Kaufmann, VLSI Digital Signal Processing Systems: Design and Implementation, Keshab K. Parhi, ISBN:Wiley, Abstract: Soft decision decoding of Reed-Solomon codes can largely improve frame errors rates over currently used hard decision decoding.
In this paper, we present a new hardware implementation for soft decoding of Reed-Solomon codes based on information set decoding. To our best knowledge this is the first hardware implementation of information set decoding for long Reed-Solomon. Secure communication systems commonly use a Reed-Solomon code as one method of jam protection.
The importance of these codes is partly due to their superior error-correcting performance, but it is equally due to the availability of efficient decoding algorithms for them.

Sahoo and K.K. Parhi, "A Low Power Correlator for CDMA Wireless Systems", Journal of VLSI Signal Processing, 35(1), pp.August An efficient method to perform Reed Solomon decoding is the Peteren-Gorenstein-Zierler (PGZ) algorithm. Digital signal processors of the TMSC DSP platform seek to exploit the data level and instruction level parallelism of algorithms by having multiple ALU units capable of working in tandem, to obtain extremely high levels of performance.
High throughput implementations. Most of the high throughput implementations of turbo decoders adopt parallel processing techniques.
An alternative approach exploited in  is based on high radix processing techniques, where throughput is improved by handling multiple trellis stages per clock cycle. A radix modified Log-MAP algorithm is implemented in  to achieve a maximum. The overall processing latency is reduced by almost 80% compared with the existing designs.
Second, we design a high-throughput LDPC decoder using layered and non-layered min-sum algorithm based on non-uniform quantization (NUQ) on an FPGA kit. A novel design and implementation of an online reconfigurable Viterbi decoder is proposed, based on an area-efficient add-compare-select (ACS) architecture, in which the constraint length and.
Efficient signal processing algorithms are important for embedded and power-limited applications since, by reducing the number of computations, power consumption can be reduced significantly. Similarly, efficient algorithms are also critical to very large scale applications such as video processing and four-dimensional medical imaging.
The proposed algorithm possesses a recursive structure so that the number of cells for computing the errata locator polynomial can be reduced.
Moreover, in our approach, only one finite field multiplication per clock cycle is required for implementation, provided an improvement in the decoding speed. And the overall architecture features.

In particular we will discuss the decoding of error-control codes as a problem in spectral estimation, and see how this viewpoint leads to the development of efficient decoder algorithms.
The Winograd FFT, a fast Berlekamp-Massey algorithm, and a time-domain Reed-Solomon decoder will be described. The Viterbi algorithm is employed in the decoding of TCM, as the modulator has memory and maximum likelihood sequence detection must thus be performed.
First, the most likely signal point in each partition is determined, i.e., we find the signal point in each sub-set that has the smallest Euclidean distance from the received signal.

Data, image, audio, and video processing, some or all of which are present in all electronic devices today, are complex programming environments. Dsp - Digital Signal Processing With. Reed-Solomon allows the system to achieve this target BER with a lower transmitter output power.
The power "saving" given by Reed-Solomon (in decibels) is the coding gain. Architectures for encoding and decoding Reed-Solomon codes. Reed-Solomon encoding and decoding can be carried out in software or in special-purpose hardware.
Reed-Solomon (RS) codes can be found in many digital communication and storage systems. Recently, significant advancements have been made on algebraic soft-decision decoding (ASD) of RS codes. Among the ASD algorithms with practical multiplicity assignment scheme, the bit-level generalized minimum distance (BGMD) decoding algorithm can achieve similar or higher coding gain with lower.
