OFDM and MC-CDMA for Broadband Multi-User Communications, WLANs and Broadcasting - Lajos (University of Southampton Hanzo

Orthogonal frequency--division multiplexing (OFDM) is a method of digital modulation in which a signal is split into several narrowband channels at different frequencies. CDMA is a form of multiplexing, which allows numerous signals to occupy a single transmission channel, optimising the use of available bandwidth.
