A new method for computation of discrete wavelet transform (DWT) is introduced. The impulse response of the FIR filter, as the main block in filter bank (FB) method, is realized such that orthonormal wavelet transform is achieved without using any multiplier as the most challenging part of the FIR filters. The occupied slices and LUTs in the FPGA realization of the proposed wavelet in comparison with those of Daubechies wavelet are decreased by %50 and %56, respectively.

适用于硬件实现的新离散小波变换

介绍了一种计算离散小波变换（DWT）的新方法。FIR滤波器的冲激响应作为滤波器组（FB）方法的主要模块，可以实现正交小波变换，而无需使用任何乘数作为FIR滤波器最具挑战性的部分。与Daubechies小波相比，所提出的小波在FPGA实现中的占用切片和LUT分别减少了％50和％56。
