摘要
首先分析了瞬时信号侦测的难点，然后分析了小波(包)分析的原理和结构。对瞬时信号的小波包分析进行了详细仿真。最后对小波包分析的硬件实现作了估算。
In this paper, the difficulty of instant signals detection were analysed., the theory, and method of wavelet packet analysis were given, the instant signals based on wavelet packet analysis were simulated by Matlab and the realization by FPGA was estimated.
