| Popis: | An adaptive repeater system for OFDM with frequency hopping control to reduce interferences is proposed. In this paper, we discuss a novel repeater to reduce the Inter Symbol Interference (ISI) caused by the delayed waves with Frequency Hopping controller in the frequency selective fading channel when the shadowing is occurred due to obstacles. The proposed system provides the solution for the shadowing, removing the interferences, results in improving the performance. An adaptive repeater system for OFDM with frequency hopping control improves the BER performance. |
