A Review on Fading {&} Roadmap to its Realization
Dinesh Sharma; R. K. Singh
In these days the wireless communication
requirements are increased according to customer
requirements. The requirements are to have high voice
quality, high data rates, multimedia features, low weight
communication devices etc. But to provide these features to
customers the wireless communication channel suffers from
some problems. The main problem is fading which occurs
due to the effect of multiple propagation paths, and the rapid
movement of mobile communication devices. In a typical
wireless communication environment, multiple propagation
paths often exist from a transmitter to a receiver due to
scattering by different objects. Signal travels in different
paths can undergo different attenuation, distortions, delays
and phase shifts. So, this is necessary to reduce the problem
of fading. One effective solution is proposed for wireless
system named diversity, with out the requirement of extra
power or extra bandwidth. This paper discusses about the
characteristics of fading models and a broad classification of
various diversity techniques.
