Overview

ABOUT THE COURSE: This course will provide an advanced level understanding of a wireless communication system. Starting with the overview of wireless systems and standards, the students will study the fundamental capacity limits of wireless channels along with transmission strategies to maximize the theoretical capacity The course will also cover fundamental coding techniques such as block, convolutional and trellis coding for wireless channels and will also touch upon the recent developments in concatenated, turbo and LDPC codes. The students will also learn the benefits of applying adaptive modulation and coding strategies in wireless channels to enable robust and spectrally efficient communication. This course will also introduce students to MIMO communications and space time block codes which will be followed by multiuser systems and networks. Finally, the course will share insights and possible technologies for the next generation of wireless communication systems. INTENDED AUDIENCE: UG and PG StudentsPREREQUISITES: Mandatory:1.
