摘要

本文研究了一种频率选择性衰落信道的先验误差校正技术。在子倍频处使用带有零值的频谱零码来避免相应频率处的衰落。在相应的衰落频率处重合频谱零点并配合其宽度，将使信道造成的误码降到最低。

Error correction of frequency-selective fading channels with spectral nulls codes

In this paper, we investigate a prior error correction technique for frequency selective fading channels. Spectral nulls codes with nulls at submultiple frequencies are used to avoid fades at the corresponding frequencies. Coincide the spectrum null at the corresponding fading frequency and playing with its wideness, will minimize the bit errors caused by the channel.
