摘要

We deal in this paper to OFDM systems operating in time and frequency selective channels. We interest in this case to the estimation of some main channel parameters such as the delay spread, the Doppler frequency and the additive noise variance. These parameters can be used for channel estimation, channel prediction and for the power control algorithm adaptation. We provide simulation results to illustrate the performance of our proposed estimation algorithms.
