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 (2015-10-22, PDF, 296KB, 下载1次)

】Based on the digital watermark and information theory, a rudimental research for the Gaussian watermark capacity is given. Considering that Gaussian distribution has the maximum uncertainty with the maximum entropy among all given second-order distributions, this paper focuses on the watermark communication process with Gaussian channel, and uses the average mutual information to analyze the communication capacity. Also the additive noise channel is introduced to expand the non-Gaussian case. The formula of maximum transmission rate for Gaussian watermark channels is given and simplified, and the 2D and 3D curves for the relationship between the distortion and channel capacity by Matlab are illustrated. It analyses the results at different distortions in two different usages of watermark. (2011-02-07, PDF, 429KB, 下载3次)
