摘要

研究了DS1速率非对称数字用户线(ADSL)信道中两种前向纠错码的应用:用于光盘的交错里德-所罗门码和Iwadare突发纠错码。推导了脉冲噪声引起的ADSL突发误差分布模型。该模型用于分析脉冲噪声存在时码的性能。还测定了具有串扰或高斯噪声的误码率，并将结果与未编码传输的误码率进行了比较。结果表明，光盘编码对ADSL是非常有效的。

Forward error correction for asymmetric digital subscriber lines (ADSL)

The application of two types of forward error correction codes to the DS1 rate asymmetric digital subscriber line (ADSL) channel is examined: interleaved Reed-Solomon codes used for compact disc, and Iwadare burst error correction codes. A model is derived for the distribution of burst errors that impulse noise causes with ADSL. This model is used to analyze the performance of the codes in the presence of impulse noise. The bit error rate with crosstalk or Gaussian noise is also determined and results are compared to those for uncoded transmission. It is found that the compact disc codes are very effective for ADSL.<>
