Multi-standard Trellis-based FEC Decoder

Résumé

Nowadays wireless standards optimize their capacity thanks to technics such as advanced Forward Error Correction (FEC) technologies like Low-Density Parity-Check and Turbo codes. Smartphone and Home automation are specific use cases where multi-standard architectures show great interest. Furthermore some standardized FEC can be interpreted as trellis codes. Trellis-based iterative algorithms are competitive to decode several codes. The goal detailed in this paper is to provide a multistandard decoder applied on 3GPP-LTE and IEEE802.11n codes. A state of the art of main decoding algorithms and on the selected codes is necessary to underline the decoding similarities and to design a trellis construction. An optimized trellis decoder followed by a common architecture are then studied and compared with existing solutions in term of performance, complexity and throughputs.
