说明：  Owing to the broad application value of audio watermarking in remote transmission and mobile extraction, it is very important to study watermarking approaches against A/D and D/A conversion. Based on wavelet decomposition and cepstrum technology, an audio watermarking algorithm is proposed where the low-frequency wavelet coefficients are chosen for cepstrum transforming. Then, the obtained cepstrum data shows stable for watermark hiding by the methods of edging data cutting and statistical mean modification. The synchronization is not required in the algorithm. Experimental results show that the proposed algorithm can resist on the attack of A/D and D/A successfully with features of large capacity and zero bit error. It will be helpful for the mobile audio in secure broadcast and management in the

本此设计主要目的是掌握并验证多址技术的相关内容，不涉及移动业务的相关技术。通过学习CDMA宽带无线通信技术，掌握直接序列扩频通信的基本理论，掌握基于LabVIEW的通信系统基本设计和仿真方法，利用LabVIEW设计一个包括发送模块和接收模块在内的简单CDMA基带通信系统，实现信号的码分多址，扩频发送和同步接收等功能。(failed to translate)
