TOP LOC 282023 Waveform

Welcome to the "Waveform" course offerd in cooperation with the Medipol University in Istanbul /Turkey.

In this program, we'll explore the fundamental concepts, design principles, and applications of waveforms and multiple access techniques in wireless communication. We'll review the wireless channel, understand waveform representations, and trace the historical development of waveforms. Orthogonal and non-orthogonal concepts will be explored, along with multicarrier versus single carrier waveforms. Discover the versatility of Orthogonal Frequency Division Multiplexing (OFDM), its advantages, and applications. We'll cover channel equalization, synchronization, and pilot designs. Explore the future of waveform design and its impact on wireless communications. Join us on this journey to gain insights into advanced waveform designs and the potential of waveforms to shape the future of connectivity.
