Description: 本文提出了一种算法，根据不同的噪声容限分配数据位，从而实现不等错误保护（UEP）。 新的方法是基于非UEP分配算法。新算法设计通过集成一个新的SNR-排序方案，可抗非平稳脉冲噪声和信道变化。仿真结果表明，该高度保护的比特流分布在低信噪比的大量载波上，从而确保由非平稳噪声信噪比引起的变化，不会多少影响这些载波。此外，窄带干扰不会干扰大量的重要数据。-This paper proposes an algorithm that distributes
bits according to different noise margin levels,
thereby realizing unequal error protection (UEP). The new
approach is based on a non-UEP allocation algorithm by
Chow, Cioffi, and Bingham. The new algorithm is designed
to be robust to non-stationary impulse noise and channel
variations by integrating a new SNR-sorting scheme. Simulation
results show that the highly protected bits are spread
over a high number of carriers at low SNR, thereby ensuring
that SNR variations due to non-stationary noise will not
influence these carriers much. Additionally, narrow-band
interference will not hit a large amount of important data
