Within the scenario of the proliferation of smart vehicles, a novel tendency is to exploit the
cooperation between vehicles to create vehicular ad hoc networks (VANETs) using the IEEE …

In Cognitive Radio (CR) networks unlicensed secondary users aim at transmitting in
licensed bands while preserving primaries from harmful interference. CR communications …

This paper describes a vision-based, low-cost line-tracking system suitable for robot or AGV
navigation in structured environments. Vehicle navigation takes advantage of the visual …

The performance of the wireless channel is affected by fading. This paper describes the
principal characteristics and modeling for different types of fading channels. Different fading …

Speech enhancement is of paramount importance in improving the intelligibility and
audibility of speech signals in an uncontrolled noisy environment over wireless …

Fading is a significant problem when transmitting a signal in radio communication channel.
Multipath propagation of the transmitted signal causes the fading. The signals from different …

In wireless communication, the signal has been conveyed by numerous indistinct
observable fact, inherent to the formation of the wireless channel. Amid these one of the key …

Noise suppression in speech signal has received great attention in signal processing
research community. However, existing methods of noise suppression such as the time …

Because of the complex electromagnetic propagation phenomena and the requirement of
more and more bandwidth, the importance of studying the wireless channel becomes more …

In this paper we present a simulation of multipath Rayleigh fading and Recian fading
channel. We have used MATLAB software for simulation. Simulation was carried out for two …
