- W1522693279 abstract "OFDM is widely known as a modulation scheme which can utilize the given frequency band very efficiently, even if the channel is distorted by multipath propagation. However, in order to improve the efficiency, a high-precision estimation technique is recommended. In this paper, we pay attention to the method which introduces 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 the FFT algorithm to make this method more effective. As a result, the proposed system performs better than the conventional system especially under fading environments, and the computational complexity is reduced." @default.
