The main feature of the orthogonal frequency division multiplex (OFDM) transceivers is to avoid intersymbol interference (ISI), particularly when the information bandwidth is wider than the channel’s coherence bandwidth. In OFDM and in more sophisticated multicarrier systems, the key idea is to decompose the channel into multiple parallel subchannels whose models are flat-fading Gaussian.

摘要

The main feature of the orthogonal frequency division multiplex (OFDM) transceivers is to avoid intersymbol interference (ISI), particularly when the information bandwidth is wider than the channel’s coherence bandwidth. In OFDM and in more sophisticated multicarrier systems, the key idea is to decompose the channel into multiple parallel subchannels whose models are flat-fading Gaussian.
