Rayleigh fadingRician fadingBit Error Rate (BERMultipath fading and motion induced fading are the two most severe performance limiting phenomena in wireless environments. In a wireless communication channel, there can be more than one path in which the signal can travel between the transmitter and ...

This paper proposes, a technique which uses chaotic communication system combined with adaptive beamforming, for secure communications and to improve the system performance by mitigating interference. For secure communications, chaotic sequences are used
With an improved Rayleigh fading model and a zero-mean stochastic sinusoid as the scattering and specular components respectively, a stochastic simulation model is proposed for the generation of Rayleigh and Rician fading waveforms. Compared with the existing stochastic models, the proposed simulator need...
When measuring antenna diversity branch envelope signals, uncorrelated noise-like signals are corrupting the desired signals (described by Rician/Rayleigh fading processes). This causes a higher degree of envelope decorrelation between the total antenna branch signals. This has a high importance in system...
In this paper the effect of three fading channel (Rayleigh, rician & shadowing) on optimal transmission power; route BER and energy consumption for successful delivery of data in multihop is studied for such randomly deployment in wireless sensor network. 展开 ...
