To introduce the concepts of wireless / mobile communication using cellular environment. To make the students to know about the various modulation techniques, propagation methods, coding and multi access techniques used in the mobile communication. Various wireless network systems and standards are to be introduced.
· It deals with the fundamental cellular radio concepts such as frequency reuse and handoff. This also demonstrates the principle of trunking efficiency and how trunking and interference issues between mobile and base stations combine to affect the overall capacity of cellular systems.
· It presents different ways to radio propagation models and predict the large – scale effects of radio propagation in many operating environment. This also covers small propagation effects such as fading, time delay spread and Doppler spread and describes how to measures and model the impact that signal bandwidth and motion have on the instantaneous received signal through the multi-path channel.
· It provides idea about analog and digital modulation techniques used in wireless communication.
· It also deals with the different types of equalization techniques and diversity concepts.. It provides an introduction to speech coding principles which have driven
the development of adaptive pulse code modulation and linear predictive coding
· It deals with advanced transceiver schemes and second generation and third generation wireless networks.
