Abstract

The present paper describes an Ultra-Wideband (UWB) communication system based on the Orthogonal Frequency Division Multiplexing (OFDM) modulation scheme. The system uses a small number of sub-carrier frequencies which allow the straightforward implementation of the OFDM modulator and demodulator without the use of Discrete Fourier Transform (DFT). An experimental RF transceiver based upon the proposed method was tested. An RF band ranging from 4.2-4.8 GHz was used. The transceiver has a demonstrated operational line-of-sight communication range of 3 m for a data rate of up to 40 Mbit/s. This system is well adapted for implementation in a low-complexity and low-power integrated circuit.
