What is SNR for OFDM?
The signal-to-noise ratio (SNR), the standard measure of analog noise attribute, is used to assess the quality of the final demodulation signals in a orthogonal frequency division multiplexing (OFDM) system. The approach is based on the statistical properties of a random process after the Fourier transform.
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.
