In order to overcome the aforementioned difficulties, a novel technology called OFDM Orthogonal Frequency Division Multiplexing was proposed. OFDM is basically a broad-band modulation scheme capable of solving most of the problems associated to multi-path fading by transmitting many narrow-band signals at the same time, namely the signals are in superposition within a wide range of frequencies.
Para solucionar en gran parte las anteriores dificultades nació OFDM Orthogonal Frequency Division Multiplexing, el cual es un esquema de modulación de banda ancha capaz de hacerle frente a los problemas de la recepción multitrayecto, transmitiendo muchas señales digitales de banda angosta en paralelo y superpuestas dentro de una banda amplia.
