• Comparison of the Efficiency of Turbo Codes with Mechanisms of Reducing the Number of Iterations

  Publikacja

  • A. Marczak

  - POLISH JOURNAL OF ENVIRONMENTAL STUDIES - Rok 2011

  The paper presents the construction of encoders and decoders turbo codes with different number of states. Simulation results of the transmission quality of the turbo codes were presented. Decoders for turbo codes have worked with a fixed number of iterations and with the mechanisms reducing the number of iterations. Data were transmitted in Outdoor to Indoor & Pedestrian B environment for data rate 384 kbps. The SOVA algorithm...

• Performance of data transmission in UMTS with turbo code about decreased number of states

  Publikacja

  • A. Marczak

  - POLISH JOURNAL OF ENVIRONMENTAL STUDIES - Rok 2007

  In the paper a structure of turbo encoder and decoder about decreased number of states has been described. The simulation results of transmission performance based on turbo coding without the reduction of the number of iterations for the uplink and downlink of WCDMA/FDD interface have been presented. The SOVA algorithm for turbo decoding has been used. The investigations have been carried out for Outdoor to Indoor & Pedestrian...

  - Rok 2016

  Artykuł opisuje próbę stworzenia modelu neuronowego wymiennika regeneracyjnego siłowni kondensacyjnej pracującego w zmiennych warunkach ruchu. Wzorzec poprawnej pracy elementów siłowni turboparowej jest pożądany w dziedzinie diagnostyki, ponieważ poprawnie pracujący model neuronowy jest w stanie zastąpić czasochłonne obliczenia bilansowe.
