Locally Adaptive Passive Error Concealment
for Wavelet Coded Images

Joost Rombaut, Aleksandra Piˇzurica, Member, IEEE, and Wilfried Philips, Member, IEEE



Abstract—

This letter presents a novel locally adaptive error concealment
method for subband coded images. For each lost low-frequency
coefficient, we estimate the optimal interpolation weights
from its neighborhood. The calculation of the interpolation weights
is optimized in the mean squared error sense, and it takes into acco ....etc

MAP EQUALIZATION AND DECODING IN WIRELESS MOBILE CODED OFDM
OBJECTIVE
 OFDM suffers extra performance degradation in multi path channels due to ICI
 Bit error rate(BER) increases with this ICI
 To reduce the BER suitable equalizer is needed.
 That equalizer should not limit the advantages of OFDM
OFDM
 Orthogonal Frequency Division Multiplexing (OFDM) is a special form of multi carrier modulation technique which is used to genera ....etc

Turned-off electric home appliances generally they still require standby power when they are plugged in. In this paper we present a way to reduce the standby power of a socket. Our socket supplies the appliances with power when the user turns them on. When the user turns them off, our socket shuts the electric power off and reduces the standby power to zero. Our design uses an MCU which receives signals from a PIR sensor which detects the user when approaching the socket and the appliances. A power detector provides an MCU to control the SSR On ....etc

Bandwidth Efficient Video Multicasting in Multiradio Multicellular Wireless Networks

Abstract—

In this paper, we propose a new mechanism to select the cells and the wireless technologies for layer-encoded video multicasting in the heterogeneous wireless networks. Different from the previous mechanisms, each mobile host in our mechanism can select a different cell with a different wireless technology to subscribe each layer of a video stream, and each cell can deliver only a ....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 frequenci ....etc
