Interleaver design for turbo codes based on the performance ofiterative decoding

Girth Analysis and Design of Periodically Time-Varying SC-LDPC Codes

Time-varying spatially coupled low-density parity-check (SC-LDPC) codes with very large period are characterized by significantly better error rate performance and girth properties than their time-invariant counterparts, but the number of parameters they require to be described is usually very large and unpractical. Time-invariant SC-LDPC codes, which can be seen as periodically time-varying codes

Transparency vs magic numbers : The development of stair design requirements in the Italian Fire Safety Code

Staircase and other structured linear-time encodable LDPC codes : Analysis and design

We consider a family of codes which can be seen both as a special kind of serial turbo codes and as LDPC codes having a parity check matrix which is partly random and partly structured. These codes are linear-time encodable, thanks to the turbo structure, and can be decoded as LDPC codes. We provide an ensemble analysis for the waterfall region, on the line of classical results for serial turbo co

Spatially Coupled Serially Concatenated Codes: Performance Evaluation and VLSI Design Tradeoffs

Analysis and Design of Tuned Turbo Codes

It has been widely observed that there exists a fundamental tradeoff between the minimum (Hamming) distance properties and the iterative decoding convergence behavior of turbo-like codes. While capacity-achieving code ensembles typically are asymptotically bad in the sense that their minimum distance does not grow linearly with block length, and they therefore exhibit an error floor at moderate-to

From Code Compliance to Holistic Approaches in Structural Design of Bridges

Forum papers are thought-provoking opinion pieces or essays founded in fact, sometimes containing speculation, on a civil engineering topic of general interest and relevance to the readership of the journal.

Evaluation of an Interleaver Design Algorithm for Turbo Codes in UMTS

Some results concerning design and decoding of turbo-codes

We consider the following problems related to the construction and analysis of turbo-codes: asymptotic behavior of interleavers (permutors), asymptotic behavior of the minimum distance, and also some examples of practical application of the developed methods to concrete turbo-codes.

Interleaver design for turbo codes with reduced memory requitement

The interleaving and deinterleaving performed in turbo codes require that the interleaver rule is either stored in memory or that it can be calculated in real time. For large interleavers, and for systems where many different interleaver sizes are used, the interleaver rule storage becomes memory demanding. This input document presents and evaluates two interleaver structures that reduce the requi
