Abstract: Turbo codes and low-density parity-check (LDPC) codes both have their advantages and can achieve the Shannon limited performance. The constituent recursive systematic convolutional (RSC) ...

This paper propose an improved method called the modified warm-up-free parallel window(PW) MAP decoding schemes to implement highly-parallel Turbo decoder architecture based on the QPP(Quadratic ...

This article focuses on techniques to decode UMTS Turbo codes efficiently using a general purpose DSP processor with MAP (maximum a posterior) decoding algorithm. Since MAP decoding is costly both in ...

Communication-system designers have always had to deal with trade-offs among data reliability, efficient use of available spectrum, data throughput, and cost. Error-correction coding (ECC) is one of ...

Turbo decoding stands as a pivotal technique in modern communications, enabling near-capacity error correction through iterative decoding processes. By combining ...

This paper describes an ASIP decoder template suitable for multi-standard Viterbi, Turbo and LDPC decoding. We show architecture fitness for WLAN, WiMAX and 3GPPLTE standards, although various other ...

Abstract: Iterative bit flipping decoders are an efficient and effective choice for decoding codes which admit a sparse parity-check matrix. Among these, sparse $(v,\ w)$-regular codes, which include ...

NEW YORK, Feb. 26 (UPI) -- New computer turbo codes promise to revolutionize telecommunications by enabling faster and more error-free data transfer rates while saving transmitters power, experts ...

TOULOUSE, France November 24, 2004 (CCSDS) – The European Space Agency (ESA) launched SMART-1 late last year making it the first satellite to have data transmissions powered by Turbo Codes, ...

Recently, the concept of small femtocell base stations has been gaining popularity in mobile applications because of their advantages over traditional macrocells in terms of coverage, compatibility, ...

Fig 1. The Swizzle encoder and decoder are shown in context, residing inside the Framer device. The framer is shown connected to a 40G or 100G OIF compliant module. Fig 2. This is a generic example of ...
