| Abstract(in English) | OFDM transmission system has a high performance under multi-path fading environment. Thus, this system is attracted and examined in the field of not only digital broadcasting but also mobile telecommunication systems. Especially, in the OFDM transmissions, we can reduce the inter symbol interference by using guard interval. But we still remain a problem which is to overcome the influence of inner symbol interference in order to realize the highly efficiency transmission system. Therefore we need the high quality estimation and equalization scheme of the multi-path fading without a complicated circuit at the receiver. This paper proposes the receiver configuration that can estimate propagation characteristic and equalize the received wave before FFT by using pilot sequence aided OFDM mobile transmission system. We simulated the BER performance of the proposed system under the multi-path fading environment. |
