Analysis of OFDM Error Floor in Indoor Channels by Stochastic Modeling

In this paper, we propose a model for estimating the error floor in a small-time- dispersion environment - typically indoor, where both channel and overall OFDM symbol are presented stochastically. The developed novel model for the error floor prediction involves modified common channel time dispersion parameters as well as the ones characterizing the OFDM signal. Its validity was confirmed by the results of the corresponding Monte-Carlo simulations.
