LDPC Decoding Software Implementation for Satellite TT&C SDR Modem Application
Celestia Antwerp is a leading company in Belgium, active in the field of satellite ground communication technology. It is part of the Celestia Technologies Group.
Celestia Antwerp’s core business is in the delivery of satellite communication solutions for the ground segment extension with products and systems. Celestia Antwerp operates both on the commercial and institutional markets, supporting space agency programs, as well as industrial company projects worldwide. The company activities have been located in Antwerp since 1962, when it was founded as part of Bell Telephone.
Type and Description
The error correction codes are widely used in digital communication systems to correct the transmission errors. The space industry, following CCSDS & ECSS standard recommendations, makes use of the LDPC (Low-Density Parity-Check code) decoding scheme to improve robustness against errors in some specific mission scenarios. Typically, this algorithm is mostly implemented with Field Programmable Gates Array (FPGA) for very high-speed receivers. Tremendous improvements have been made to CPU architectures (e.g. SIMD (Single Instruction on Multiple Data)) and Graphics Processing Units (GPU) offering excellent throughput performance on vectorized mathematic operations through a high degree of parallel computations. Without reaching the performance level of FPGA, these improvements however allow to fulfill the growing rate requirements for Telemetry, Tracking and Command (TT&C) equipment. Hence, the scope of this project is to develop a Software library for high-speed LDPC decoding taking benefits of
Objective and Deliverables:
The objective of this thesis consists in the development of parallelized software libraries (AVX (preferred), GPU or multithreading) for efficient LDPC decoding (CCSDS 131.0-B-3). He/She shall finish this activity with a presentation to a mixed audience of academical & industrial experts.
The following deliverables are expected:
The following will be taken into account for the final evaluation.
