摘要: We address the impact of a too short cyclic prefix on multicarrier systems such as orthogonal frequency division multiplexing (OFDM) and discrete multitone (DMT). The main result is that intersymbol interference (ISI) intercarrier (ICI) may be spectrally concentrated analytical expressions showing this are given. A practical implication is, e.g., in some xDSL can surprisingly short, shown one example ADSL transmission.
