A finite-state simulation model for OFDM over frequency-selective fast fading channels

In this paper, a computationally efficient, algorithmically simple simulation model for transmission of orthogonal frequency division multiplexing (OFDM) signals over time-variant, frequency-selective wireless propagation channels is proposed. The considered approach is based on applying a set of finite-state models with parameters derived explicitly from propagation channel and transmission system characteristics. The validity of the proposed model is studied using theoretical capacity analysis, and by comparing results with simulations performed using a reference propagation model. The obtained results indicate good performance with all considered criteria.
