Abstract

An OFDM is widely known as a modulation scheme which can utilize the given frequency band very efficiently, even if the channel is distorted by the multi-path propagation. However, in order to improve the efficiency, high-precision estimation technic is recommended. In this paper, we pay attention to the method which introduce a condition based on the propagation path model in order to obtain better precision. Although this method performs better than another conventional method especially under the fading environment, this method has large computational complexity. Hence, we simplify this method by using FFT algorithm to make this method more effective. As the result, proposed system performs better than the conventional system especially under the fading environment, and computational complexity was reduced in the simplified system less than the conventional system.
