Flexible and high-efficiency turbo product code decoder design
This paper presents a flexible and high-efficiency decoder for turbo product code using extended Hamming code. The supported component code ranges from (8, 4) to (128, 120) to provide enough flexibility for various communication standards. A novel Chase decoder architecture is developed with high efficiency using a low complexity algorithm. Moreover, a conflict free interleave memory access mod...
متن کاملTurbo Product Code Decoder Without Interleaving Resource: From Parallelism Exploration to High Efficiency Architecture
This article proposes to explore parallelism in Turbo-Product Code (TPC) decoding through a parallelism level classification and characterization. From this design space exploration, an innovative TPC decoder architecture without any interleaving resource is presented. This architecture includes a fully-parallel SISO decoder capable of processing n symbols in one clock period. Syntheses results...
متن کاملAn Analog Turbo Decoder for an (8,4) Product Code
This paper illustrates how analog circuitry can be used to decode turbo and turbo-like codes. For ease of exposition, the focus is on a simple two dimensional product code comprised of a 2 by 2 array of (3,2) single parity check codes. It is shown that the heart of the decoder is a soft exclusive-or operation which is easily implemented in analog as a modified Gilbert multiplier. Finally, a com...
متن کاملReed-Solomon Turbo Product Codes for Optical Communications: From Code Optimization to Decoder Design
Turbo product codes (TPCs) are an attractive solution to improve link budgets and reduce systems costs by relaxing the requirements on expensive optical devices in high capacity optical transport systems. In this paper, we investigate the use of Reed-Solomon (RS) turbo product codes for 40 Gbps transmission over optical transport networks and 10 Gbps transmission over passive optical networks. ...
متن کاملA High Performance Serially Mixed SOVA Decoder for Turbo Code
The backward direction Soft Output Viterbi Algorithm (a backward SOVA) is compared with the conventional SOVA (a forward SOVA) in turbo code decoding. We find noticeable performance improvement for the backward SOVA when it is not terminated, which turns out to be due to a smaller reliability value, indicating that the termination conditions of the turbo encoder strongly affect the performance ...
