With the advent of multimedia, digital signal processing (DSP) of sound has emerged from the shadow of bandwidth-limited speech processing. Today, the main appli- cations of audio DSP are high quality audio coding and the digital generation and manipulation of music signals. They share common research topics including percep- tual measurement techniques and analysis/synthesis methods. Smaller but nonetheless very important topics are hearing aids using signal processing technology and hardware architectures for digital signal processing of audio. In all these areas the last decade has seen a significant amount of application oriented research.

opnet中zigbee协议下经常需要进行节能研究，需要添加电池模块。 ZigBee网络是资源受限的网络, 集中表现在电池能量、数据整合能力、存储空间及通信带宽等非常有限。终端节点采集的原始数据直接传送到路由节点是现在普遍采用的方法，但由于原始数据信息冗余性的存在会浪费有限的电池能量和通信带宽；频繁的信道竞争也会降低信息收集的效率。物理层和MAC层是ZigBee协议射频芯片硬件实现的，所以数据融合只能与网络层和应用层相结合。由于数据融合和网络层相结合带来的跨层的问题给协议栈的实现带来很多困难。
