摘要：In this paper, a new energetic approach was developed to study the impact of synchronization errors on OFDM transmission systems. Indeed, this approach can be applied in wireless communication systems such as HiperLAN and WLAN Transceivers. Firstly, the studies were conducted on the impact of timing errors on system performance and we have shown that stress recovery sampling frequency were particularly hard because of the use of a minimum number of pilot symbols and a maximum number of states of the constellations. The mathematical approach we followed in this paper which is an original contribution in the RF field can jointly estimate the channel response and the frequency offset. We realized, along with mathematical analysis, simulations to evaluate the performance of our approach. The results can evaluate the performance of the system against synchronization effects.
