OFDM implementation

Orthogonal frequency-division multiplexing (OFDM) is a multi-carrier modulation system where data is transmitted as a combination of orthogonal narrowband signals known as subcarriers . OFDM builds upon single carrier modulation such as QAM and can transmit at similar data rates.

Orthogonal frequency-division multiplexing is a method of data transmission where a single information stream is split among several closely spaced narrowband subchannel frequencies instead of a single Wideband channel frequency .

Orthogonal frequency division multiplexing (OFDM) takes a digital information signal with bit rate Rb, maps n-bit words on to M = 2n symbols (each symbol being a complex number representing the amplitude and phase of an M-ary modulation scheme ), splits the resulting symbol stream (rate Rs = Rb/n) into N parallel …
