说明：  提供了三套ZigBee兼容的 平台，为我们的客户提供一种 只需要添加应用的解决方案。 所有的三种解决方案都是建立 在CC2420/CC2520上，而且 有很好的共存性。这些兼容的 平台缩短了产品进入市场的时 间，简化了系统设计和ZigBee 终端产品的验证。(Provided three sets of ZigBee-compliant platform, to offer our customers only need to add the application of a solution. All three solutions are built on CC2420/CC2520, but also the co-existence of good. These platform compatible product to shorten time-to-market and simplifies the system design and test ZigBee end-products.)

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
