OFDM White Paper
Orthogonal frequency division multiplexing (OFDM) is a form of digital modulation used in a wide array of communications systems. OFDM is spectrally efficient, carrying more data per unit of bandwidth than such services as GSM and W-CDMA. OFDM tolerates environments with high RF interference. Finally, OFDM works well in harsh multi-path environments, This white paper explains what OFDM is, why it’s important, where it’s used, and what test instrumentation is required to maintain it.
