Performance Analysis of High Throughput MAP Decoder for Turbo Codes and Self Concatenated Convolutional Codes

IEEE Access, 2019
The effect of parallelism on Bit Error Rate (BER) performance of Turbo Code (TC) and Self Concatenated Convolutional Code (SECCC) with different levels of parallelism and frame sizes is investigated. Next Iteration Initialization (NII) method is employed

Dynamically generated concatenated codes and their phase diagrams

Physical Review Research
We formulate code concatenation as the action of a unitary quantum circuit on an expanding tree geometry and find that for certain classes of gates, applied identically at each node, a binary tree circuit encodes a single logical qubit with code distance

An Improved Concatenation Scheme of BCH-Polar Codes With Low-Latency Decoding Architecture

IEEE Access, 2019
Polar codes have drawn much research attention in the last ten years for their capacity-achieving property. However, their conventional successive cancellation decoding method performs not well at a short or moderate length.

Parallel and Serial Concatenated Single Parity Check Product Codes

EURASIP Journal on Advances in Signal Processing, 2005
The parallel and serial concatenation of codes is well established as a practical means of achieving excellent performance. In this paper, we introduce the parallel and serial concatenation of single parity-check (SPC) product codes.

Concatenated parity and turbo codes

Electronics Letters, 2001
Turbo codes have an error floor that is caused by low-weight error events. Here, it is shown that a concatenated code with a simple rectangular parity-check outer code and a turbo inner code can significantly reduce the error floor. It is also shown that in several situations, the concatenated parity-check and turbo code performs significantly better ...

Deterministic Generation of Concatenated Graph Codes from Quantum Emitters

PRX Quantum
Photon loss is the dominant noise mechanism in photonic quantum technologies. Designing fault-tolerant schemes with high tolerance to loss is thus a central challenge in scaling photonic quantum information processors.

Design and Evaluation of Adaptive (Serial/Parallel) Concatenated Convolutional Codes

Journal of Engineering and Sustainable Development, 2006
In this paper, parallel Concatenated Convolutional Codes (PCCCs) is modeled as a special case of Serial Concatenated Convolutional Code (SCCCs). Consequently, resulting in Adaptive (parallel/serial) concatenated convolutional code in which the same ...

Some Extended Results on the Design of Punctured Serially Concatenated Convolutional Codes

Journal of Communications Software and Systems, 2006
The aim of this paper is twofold. On one hand, it presents the results of the search for good punctured systematicrecursive convolutional encoders suitable for application in serially concatenated convolutional codes (SCCCs) operating in two different ...
