Abstrakty

PL

Dokonano przeglądu różnych sposobów podejścia do problemu korekcji zniekształceń liniowych w systemach z modulacją OFDM, pomijając szczegółowe aspekty implementacji zaprezentowanych rozwiązań. Omówiono charakterystyczne cechy metod korekcji w dziedzinie czasu i częstotliwości z uwzględnieniem także algorytmów nienadzorowanych.
