Lecture 04

Welcome to the fourth lecture of our series on 5G wireless standard design. This lecture will cover how cellular networks serve thousands of users simultaneously. We will discuss Orthogonal Frequency-Division Multiplexing (OFDM), the waveform used in 5G systems, and the corresponding transmitter and receiver architectures. Additionally, we will explain how Orthogonal Frequency-Division Multiple Access (OFDMA) technology is used in 5G to serve multiple users at once.
