Wireless networks have expanded beyond person-to-person communications, connecting not only users but also machines, devices, and objects. Using over 200 illustrative slides, this course will cover the fundamental principles of digital communications. Participants will learn how to analyze the performance of digital modulation techniques such as quadrature amplitude modulation (QAM) and apply them in modern wireless systems. High-order modulation (such as 256-QAM, 1024-QAM) achieves greater spectral efficiency, thus leading to higher data rates. They form the basis of current and emerging wireless standards (such as 5G and Wi-Fi). By changing the modulation and coding, the available data rate and robustness of the wireless signal can be adapted to deployment conditions.
