A Novel Transceiver Architecture Based on Wavelet Packet Modulation for UWB-IR WSN Applications

Abstract

In last few years, several recent developments concern a new proposed techniques of communication for WSN (Wireless Sensors Network) using a complex methods and technics. This network is considered a future platform for many applications like: medical, agriculture, industrial, monitoring and others. The challenge of this work consists in proposing a new design of transceiver for WSN based on IDWPT (Inverse Discrete Wavelet Packet Transform) in emitter and DWPT (Discrete Wavelet Packet Transform) in receiver for mono and multi users using AWGN Channel. We will propose in this paper, a new concept of impulse radio communication for multiband orthogonal communication for UWB (Ultra-wideband) applications. The main ob-jective of this work is to present a new form of pulse communication adapted to low throughput short-range applications and is scalable according to the type of use but also the number of sensors.
