Języki publikacji
Abstrakty
Artykuł dotyczy projektowania systemów kodowania korekcyjnego dla protokołów komunikacyjnych w Internecie Rzeczy, które są implementowane na platformach o mocno ograniczonych zasobach obliczeniowych. W artykule zaproponowano wykorzystanie nowoczesnych kodów LDPC (Low Density Parity Check), zaprezentowano algorytm dekodujący oraz przedstawiono wyniki eksperymentalne implementacji w układzie mikrokontrolera. Przeprowadzono testy dla różnych wielkości słów kodowych oraz zebrano wyniki związane z czasem dekodowania, przepustowością jak również liczbą iteracji potrzebną do zdekodowania jednego bloku.
The article concerns the design of correction coding systems for communication protocols in the Internet of Things, which are implemented on platforms with very limited computing resources. The article proposes the use of modern LDPC (Low Density Parity Check) codes, presents the decoding algorithm and presents the experimental results of the implementation in a microcontroller device. Experiments were performed for different codeword sizes and the results were collected concerning the decoding time, throughput as well as the number of iterations needed to decode one block.
