摘要
无线传感器有几个缺点,如发射距离短,计算处理能力差,以及发射功率低等。该文以协作信号处理概念为理论基础,讨论设计高效传感器网络。设想有一个由多个传感器节点组成的网络,每个节点与一个处理器对应。通过采用一种适当的协作运算法则和通信设计,把传感器当作分布式数字信号处理器(DDSP,Distributed Digital Signal Processor)使用,将DDSP用于快速傅里叶变换,使无线传感器网络性能得到提高。
Wireless sensor has several disadvantages such as the short transmission distance, poor computing capability and low transmitting power. In this paper, the collaborative signal processing concepts as the theoretical foundation to discuss the design of a high performance sensor network. Imagine having a plurality of sensor nodes, each node with a corresponding processor. By adopting an appropriate cooperative algorithm and design for communication, the sensor as a distributed digital signal processor （DDSP -Distributed Digital Signal Processor）, DDSP for fast Fourier transformation, makes the performance of wireless sensor network is improved.
