HLDPC Codes – Low Density, Low Complexity, Efficient Erasure Correcting Codes

Kristian Nybom, Jerker Björkqvist, HLDPC Codes – Low Density, Low Complexity, Efficient Erasure Correcting Codes. In: Proceeding of the 13th European Wireless Conference, 2007.

Abstract:

In this paper we introduce an error correcting code, which is designed to be used for providing error free data object transmissions over noisy wireless data casting systems, such as DVB-H. The code belongs to the class of low-density parity-check (LDPC) codes, and uses multiple parallel code structures, also called hyper codes. We also provide a straightforward algorithm for generating the parity-check matrix, which can generate instances of the code for different code sizes and coding capabilities, using only a few parameters, hence giving us flexibility in designing the data transmission system. Using simulations and field measurements we show that the code performance is similar to that of the current state of the art codecs. The coding and decoding complexities are low, enabling software-based use in energy-constrained mobile devices.
