What is OFDM: Efficient Wireless Data Transmission about?
Chapter 4 discusses Orthogonal Frequency Division Multiplexing (OFDM), a modulation scheme that efficiently transmits digital data over radio channels, particularly in multipath environments. OFDM utilizes multiple narrow bandwidth carriers that are orthogonal to avoid interference, offering advantages like high spectral efficiency and robustness against channel fading, though it faces challenges such as high peak-to-average-power ratio and susceptibility to phase noise. The chapter also covers OFDM
