Low-Complexity VLSI Hardware Design for DWPT
Abstract: AbstractThis paper presents a low-complex discrete wavelet packet transform (DWPT) architecture design for power constrained and cost sensitive healthcare applications. The multiplier-adder unit of the proposed multiplier-based designs of DWPT is replaced by the shift-add unit to reduce the area complexity of parallel structure. The proposed low-complexity multiplier-less design could be used an alternative to the existing multiplier-based design for hardware efficient realization of multi-level DWPT.Keywords: DWPT, Hardware complexity, VLSI, …

Phase Noise Reduction in WLAN by Applying Wavelet Packet Multiplexing
Abstract: The IEEE 802.11 standards for wireless Local Area Networks (LANs) commercialized as Wi-Fi are deployed in office and home environments. These systems provide data rates up to 1300 Mbps at 5 GHz and 400 Mbps at 2.4 GHz with physical layer based on OFDM and MIMOOFDM. Traditionally, multiplexing in OFDM is realized using static orthogonal waveforms derived from Fourier transforms. The decoding of the data at receiver is based on …

A Review of Dynamic Wireless Charging System for Electric Vehicles and IoT Technology
Abstract: Dynamic charging of Electric Vehicles (EVs) by Wireless Power Transfer (WPT) is a key emerging technology in the field of power electronics. Even though Electric vehicles (EVs) are beneficial to the environment, they have their own limitations with respect to charging difficulties and mileage anxiety. These problems are overcome by dynamic wireless power transfer (DWPT) technology. By DWPT technology the size of the main storage battery can be reduced, significantly …
