What is OFDM transmitter and receiver?
An OFDM signal consists of a number of closely spaced modulated carriers. When modulation of any form – voice, data, etc. is applied to a carrier, then sidebands spread out either side. It is necessary for a receiver to be able to receive the whole signal to be able to successfully demodulate the data.
Which transform techniques can be used in OFDM transmitting and receiving systems?
The inverse fast Fourier transform can therefore be used to realise the basic OFDM signal at the transmitter and the FFT can be used to recover (de-multiplex) the symbols at the receiver.
What is OFDM transmitter?
In telecommunications, orthogonal frequency-division multiplexing (OFDM) is a type of digital transmission and a method of encoding digital data on multiple carrier frequencies.
What is OFDM radio?
What is orthogonal frequency-division multiplexing (OFDM)? 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.
