【应用手册】Implementing OFDM Modulation for Wireless Communications
This application note discusses various implementation schemes for
orthogonal frequency division multiplexing (OFDM) modulation and
demodulation. The focus of this application note is cyclic prefix (CP)
insertion and removal.
Desired Knowledge
You should have a basic knowledge of OFDM systems before learning the
operation of cyclic prefix insertion and removal.
The methods proposed in this application note use the Altera® fast
Fourier transform (FFT) MegaCore® function. You should have a basic
knowledge of the FFT MegaCore function and Avalon® Streaming
Interface.
