no open-source, optimized implementations of such applications available. In this paper, we present the design and implementation behind the creation of an optimized MPEG-2 software decoder for this unique parallel architecture, and demonstrate its performance through an experimental study

, assuming full parallelization. We show that multiple folded SCD can be effectively implemented for up to κ = 3 foldings due to memory limitations. This decoder achieves exactly the same performance of the original SCD with signifi-cantly reduced latency. Index Terms—Polar codes, SC decoder, folding

Abstract — Turbo codes are widely used in many radio systems due to its superior performance and Software Radio (SR) is an emerging paradigm of the wireless communication system design due to its good flexibility and adaptability. However, since turbo decoding is computationally intensive, the SR

Abstract — Many implementations for decoding LDPC codes are based on the (normalized/offset) min-sum algorithm due to its satisfactory performance and simplicity in operations. Usually, each iteration of the min-sum algorithm contains two scans, the horizontal scan and the vertical scan. This paper

on generic x86 Central Processing Units (CPUs) is practical. Thanks to recursive decoding, they exhibit excellent decoding speed, much higher than large, irregular Low Density Parity Check (LDPC) codes implemented on similar hardware, and competitive with implementations of the same codes on high-end Graphic

Turbo codes are the most recent breakthrough in coding theory. However, the decoder's implementation cost limits their incorporation in commercial systems. Although the decoding algorithm is highly data dominated, no true memory optimization study has been performed yet. We have extensively

. Although network coding increases the network performance, the complexity of the network coding decoder algorithm is still high, especially for higher dimensional finite fields or larger network codes. Different software and hardware approaches were proposed to accelerate the decoding algorithm

Objects are coded and transmitted separately and composed at the decoder site, letting the receiver interact and influence the way the scene is presented on the receiving display and speakers.

mechanisms used in several popular applications. This can be used to encode data in multiple formats or even the same format with different content. Implementation details of the decoder or environmental differences decide which data the decoder locks onto. This leads to different users receiving different
