OFDM Phase Tracking

This lecture covers the estimation and correction of Carrier Frequency Offset (CFO) in Orthogonal Frequency Division Multiplexing (OFDM) systems. It explains the use of preambles for CFO estimation, residual CFO correction, and phase tracking. The lecture also delves into the challenges of residual Sampling Frequency Offset (SFO) and the importance of accurate phase estimation. Additionally, it discusses the process of putting together OFDM at the transmitter and receiver, including CFO correction, channel estimation, and symbol detection. The lecture concludes with an overview of wireless data rates, coding schemes, and multiple access protocols.
