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). |
