VLSI DESIGN OF DISCRETE WAVELET PACKET TRANSFORM FOR OPTIMIZED WIRELESS LOCAL AREA NETWORK COMMUNICATION SYSTEMS

Abstract

The rapid growth of wireless communication technologies has significantly increased the demand for highspeed, reliable, and energy-efficient Wireless Local Area Network (WLAN) systems. Conventional WLAN communication architectures often experience limitations in bandwidth utilization, signal quality, computational efficiency, and adaptability to dynamic channel conditions. To overcome these challenges, this paper presents a Very Large-Scale Integration (VLSI) based implementation of the Discrete Wavelet Packet Transform (DWPT) for optimized WLAN communication systems. The proposed architecture utilizes the multi-resolution analysis capability of DWPT to efficiently decompose wireless signals into multiple frequency sub-bands, enabling enhanced signal representation, noise suppression, and bandwidth utilization. Unlike traditional signal processing techniques, the proposed DWPT-based framework provides improved adaptability to varying channel characteristics while maintaining signal integrity and communication reliability. The architecture is model using Hardware Description Language and implemented on an FPGA platform to achieve high-speed processing with reduced hardware complexity. The proposed VLSI design incorporates optimized filter bank structures, parallel processing modules, and pipelined computation units to improve throughput and reduce latency. Performance evaluation demonstrates significant improvements in spectral efficiency, signal quality, resource utilization, and power consumption compared to conventional WLAN processing methods. Furthermore, the proposed design exhibits excellent scalability and robustness, making it suitable for next-generation wireless communication systems, Internet of Things (IoT) devices, smart networking applications, and high-speed data transmission environments. The results confirm that the integration of Discrete Wavelet Packet Transform with VLSI technology provides an effective solution for enhancing WLAN performance while maintaining low-power operation and compact hardware implementation.
