Abstract

Comparative studies on DWT-OFDM and FFTOFDM systems are presented. The model for DWT-OFDM includes zero-padding and vector transpose for transmitting the OFDM signal. MATLAB simulation commands are also described. The discrete wavelet transform-OFDM (DWT-OFDM) has to satisfy the orthonormal bases and the perfect reconstruction properties to be considered as wavelet transform. Different wavelet families have been used and compared with the conventional F ....etc

Turbo TCM Coded OFDM Systems for Non-Gaussian Channels



I. INTRODUCTION
Orthogonal Frequency Division Multiplexing (OFDM)
modulation has been a promising solution for efficiently
capturing multipath energy in highly dispersive UWB channels
and delivering high data rate transmission. The main
idea behind OFDM is to split the transmitted data sequence
into N parallel sequences of symbols. The transmission is
carried out in parallel on different frequencies which is a
desirab ....etc

Channel Estimation for OFDM System with Two Training Symbols Aided and Polynomial Fitting



INTRODUCTION

ORTHOGONAL frequency division multiplexing
(OFDM) is a high spectral efficiency transmission
scheme. It divides a wideband signal into many orthogonal
subcarriers and induces a symbol period that is much
longer than the bit duration. However, a long symbol
period is sensitive to the time-varying channel in wireless
communications. The channel response might change during

If the secondary coil is attached to a load that allows current to flow, electrical power is transmitted from the primary circuit to the secondary circuit.Ideally,the transformer is perfectly efficient; all the incoming energy is transformed from the primary circuit to the magnetic field and into the secondary circuit. If this condition is met, the incoming electric power must equal the outgoing power.
Pincoming = IPVP = Poutgoing = ISVS

giving the ideal transformer equation

Abstract
In the presented paper, the principle of frequency domain channel estimation for wireless OFDM systems will be shown. A well known noise reduction technique will be adapted to HIPERLAN/2 and IEE802.11a standards, and its positive effects will be demonstrated by simulation results. Channel tracking has not been considered by the WLAN standards named above, although it is well known that time-variant indoor radio channels can change their characteristics within one PHY burst. This paper presents some techniques for decision directed ....etc
