Description: MP3音频流数字水印方案，试验表明该方案能得到较高的嵌入容量，对原始音频信号的改变较小，具有较好的隐形性，完整水印提取时间短，可以在音频播放过程中同步完成。通过对算法的进一步研究，我们发现可以利用插件技术将算法嵌入了当前的主流播放器中，从而实现水印信息的实时嵌入和提取。这可能成为保护网络音频版权、网络秘密通讯的一种可行的、低成本的解决方案。
-MP3 audio streaming digital watermarking program, experiments show that the program can be embedded in a higher capacity, the original audio signal changes in smaller, has better stealth, and integrity of the watermark extraction time is short, you can sync audio player to complete the process. Algorithm by further studies, we found that plug-in technology can make use of the algorithm embedded in the mainstream of the current players in order to achieve real-time information watermark embedding and extraction. This may be the protection of network audio copyright, secret communications networks as a viable, low-cost solution. Platform: |

Description: Digital signal processing (DSP) algorithms exhibit an increasing need for the
e#cient implementation of complex arithmetic operations. The computation of
trigonometric functions, coordinate transformations or rotations of complex valued
phasors is almost naturally involved with modern DSP algorithms. Popular application
examples are algorithms used in digital communication technology and in
adaptive signal processing. While in digital communications, the straightforward
evaluation of the cited functions is important, numerous matrix based adaptive
signal processing algorithms require the solution of systems of linear equations, QR
factorization or the computation of eigenvalues, eigenvectors or singular values. All
these tasks can be e#ciently implemented using processing elements performing vector
rotations. The COordinate Rotation DIgital Computer algorithm (CORDIC)
offersthe opportunity to calculate all the desired functions in a rather simple and
elegant way. Platform: |
