Computational time and hardware resource are key issues in hardware implementation of any signal-processing algorithm. This paper presents the design and implementation of a polyphase-decomposition-based new architecture of wavelet filter for power system harmonics estimation using discrete wavelet packet transform (DWPT). Usually, DWPT provides coefficients as the output; however, the proposed architecture...
Different digital media used by steganography to carry secrete information. This paper presents an algorithm to perform image steganography by combinational approach of genetic algorithm and trained auto associative neural network (TAANN). The proposed algorithm reduce needed time and needed space at encryption and at decryption level because of memory holding ability of neuron of auto associative...
Implementation of discrete wavelet packet transform on field-programmable gate array (FPGA) device for the estimation of power system harmonics is proposed in this paper. This approach provides implementation of signalprocessing algorithm using db20 as a wavelet filter, which facilitates estimation of power system harmonics very efficiently. The discrete wavelet packet transform (DWPT) decomposes...
