چکیده

The performance of a wireless signal propagation can be estimated with the properties or characteristics of the channel. This paper begins with the classification of the important characteristic of a channel i.e, fading. After that fast fading modeling for multipath with no direct path and multipath with direct path is analyzed in the fourth part of this paper. In the last section of this paper, by considering motion of the fast fading channel, plot is developed for Doppler fading channel with multiple paths.

A Secure Chaos-Based Communication Scheme in Multipath Fading Channels Using Particle Filtering

In recent years chaotic secure communication and chaos synchronization have received ever increasing attention. Unfortunately, despite the advantages of chaotic systems, Such as, noise-like correlation, easy hardware implementation, multitude of chaotic modes, flexible control of their dynamics, chaotic self-synchronization phenomena and potential communication confidence due to the very dynami...

A Blind Hammerstein Diversity Combining Technique for Flat Fading Channels

Diversity combining techniques play an important role in combating the destructive effects of channel fading in wireless communication systems. In this work we present a blind diversity combining technique for Rayleigh flat fading channels based on Hammerstein type filters. We show that the performance of this technique is very close to ideal MRC system which is accepted as an optimum receiver ...

Extension of the Coverage Region of Multiple Access Channels by Using a Relay

From practical and theoretical viewpoints, performance analysis of communication systems by using information-theoretic results is important. In this paper, based on our previous work on Multiple Access Channel (MAC) and Multiple Access Relay Channel (MARC), we analyze the impact of a relay on the fundamental wireless communications concept, i.e., coverage region of MARC, as a basic model for u...

Secure Communication in Shotgun Cellular Systems

In this paper, we analyze the secure connectivity in Shotgun cellular systems (SCS: Wireless communication systems with randomly placed base stations) by Poisson intrinsically secure communication graph (IS-graph), i.e., a random graph which describes the connections that are secure over a network. For a base-station in SCS, a degree of secure connections is determined over two channel models: ...

Performance analysis of space-time codes over correlated Rayleigh fading channels

The potential for capacity increase in multiantenna wireless communication systems has drawn considerable attention to space-time codes. However, most of the existing space-time code construction methods have assumed ideal channel models: either quasi-static fading or fast fading. In this work, we derive the performance criteria for space-time coded wireless communication systems taking into ac...
