Description: Interference evaluation of Bluetooth and IEEE 802.11 b systems-The emergence of several radio technologies, such as Bluetooth and IEEE 802.11, operating
in the 2.4 GHz unlicensed ISM
frequency band, may lead to signal interference and result in significant performance
degradation when devices are colocated in the same
environment. The main goal of this paper is to evaluate the effect of mutual interference
on the performance of Bluetooth and IEEE 802.11b
systems. We develop a simulation framework for modeling interference based on detailed MAC
and PHY models. First, we use a simple
simulation scenario to highlight the effects of parameters, such as transmission power,
offered load, and traffic type. We then turn to more
complex scenarios involving multiple Bluetooth piconets and WLAN devices. Platform: |

As a result of similar methods, only a method of choice to achieve band-stop filter, select the time being Chebyshev band-stop filter Ⅱ.

Description: Digitized images have replaced analog images as photographs or x-rays in many different fields. In their raw form, digital images require a tremendous memory capacity for storage and large amount of bandwidth for transmission. In the last two decades, many researchers have been devoted to develop new techniques for image compression. More recently, wavelets have become a cutting edge technology for compressing the images by extracting only the visible elements. In this paper a wavelet based image decomposition algorithm has been implemented. Also, a nonuniform threshold technique based on average intensity values of pixels in each sub band has been proposed to remove the insignificant wavelet coefficients in the transformed image. Experimental results are obtained to compare the Daub2, Daub3 and Daub4 compactly supported (Daubechies) orthogonal wavelets on various test images using two important performance parameters – compression ratio and PSNR Platform: |
