OFDM är en akronym för Ortogonal frekvensdelningsmultiplex, men används som en digital modulationsmetod. OFDM innebär att den information som ska överföras delas i flera parallella dataströmmar, som får modulera var sin underbärvåg. På så sätt delas frekvensspektrum upp i ett antal smalbandiga kanaler. Den främsta fördelen med OFDM framför konventionell enkelbärvågsmodulation är att det underlättar hantering av dämpning, fasvridning och störninga…
