802.11 OFDM PHY baseband implementation
Time-domain output for Annex G example of the standard. Blue = real, green = imaginary. Click on image for full-sized version.
What is it?The IEEE 802.11a wireless networking standard defines a high-rate modulation scheme named "Orthogonal Frequency Division Multiplexing" (OFDM). The 802.11g standard uses the same OFDM scheme. Just for fun I did an implementation of the OFDM transmitter and receiver, as a C model and executable code callable from MATLAB (as Mex files).
