What is OFDM demodulation?
OFDM Demodulation
An OFDM demodulator demultiplexes a multi-subcarrier time-domain signal using orthogonal frequency division multiplexing. OFDM demodulation uses an FFT operation that results in N parallel data streams.
Which of the Transform techniques can be used in OFDM Trasmitting and Reciveing 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.
How is OFDM implemented?
In a digitally implemented OFDM system, the input bits are grouped and mapped to source data symbols that are a complex number representing the modulation constellation point (e.g., the BPSKBinary phase shift keying - A type of phase modulation using 2 distinct carrier phases to signal ones and zeros. or QAM symbols ...
What is OFDM in wireless communication?
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.
