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 objective of this work is to present a new form of pulse communication adapted to low through-put short-range applications and is scalable according to the type of use but also the number of sensors.
Highlights
The Wide-Band or Ultra-Wide Band applications such as the multimedia services based generally on wireless sensors systems [1]-[5]
The challenge of this work consists in proposing a new design of transceiver for Wireless Sensor Networks (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 additive white Gaussian noise (AWGN) Channel
We suggest using the IDPWT as an impulse generator for the emitter: the corresponding synthesis filter bank will generate a wavelet whose shape depends on the data at the 2i inputs of the filter bank, i being the resolution level of the transform
Summary
The Wide-Band or Ultra-Wide Band applications such as the multimedia services based generally on wireless sensors systems [1]-[5]. Several techniques are proposed in literature especially for digital communication based on two systems: narrow-band and multi-carrier [6]-[8]. This last are developing different technique in transmitter and receiver like Modulation, MAC protocol, Equalization, Filtering, Fading, Multi-path, and Non-Line-Of-Sight (NLOS) [7] [9]. Other distribution of this system named IR (Impulse Radio), present all data in impulse form.
