| 中文摘要 | Channel estimation is the basis of data demodulation and equalization in orthogonal frequency division multiplexing (OFDM) technology. On the basis of analyzing the characteristics of power line channel, the performance of estimation algorithm, is researched when dispersed pilot frequency technology is used. Because the anti-noise interference capability of this algorithm is weak, an improved algorithm to raise the estimation accuracy by truncating the length of impulse response in time domain is proposed. In the environment of power line channel it is proved that the proposed algorithm possesses good estimation performance. |
