OFDM Error Floor Prediction in a Small-Time- Dispersion Channel

In this paper, a novel error floor prediction model is proposed for estimating the peak performance of the OFDM transmission in a small-time-dispersion environment—typically indoor. The obtained analytical formula involves both the accordingly modified common channel time-dispersion parameters such as the rms delay spread, but distinct for the advanced and delayed multipath echoes (with respect to the chosen sampling instant), as well as the OFDM signal-specific parameters. The validity of the model was confirmed by the results of the corresponding Monte-Carlo simulations.
