OFDM, orthogonal frequency-division multiplexing, is a widely used digital modulation method in wireless communications, such as WLAN, LTE, DVB-T, and 5G.OFDM belongs to the class of multicarrier modulation schemes. The earlier version of this NS-2 add-on (for OFDM PHY) was developed at NIST. At the WiMAX Forum Plenary Meeting at Hawaii (January 30 - February 2, 2007), the decision to merge the independent development efforts supported by Application Architecture.
Book Description:
MIMO-OFDM is a key technology for next-generation cellularcommunications (3GPP-LTE, Mobile WiMAX, IMT-Advanced) as well as wireless LAN (IEEE 802.11a, IEEE 802.11n), wireless PAN (MB-OFDM), and broadcasting (DAB, DVB, DMB). In MIMO-OFDM Wireless Communications with MATLAB, the authors provide a comprehensive introduction to the theory and practice ofwireless channel modeling, OFDM, and MIMO, using MATLAB programs to simulate the various techniques on MIMO-OFDM systems. One of the only books in the area dedicated to explaining simulation aspects.
SER Simulation for OFDM Link
This example shows how to perform a symbol error rate (SER) simulation of an over-the-air OFDM communication link.
A basic communications link using OFDM modulation with QPSK symbols is simulated. There is a single transmit and a single receive antenna.

Run the simulation over 10000 OFDM frames (530000 symbols). During loop execution, generate a random data vector with length equal to the required number of symbols per frame, Apply QPSK modulation and then apply OFDM modulation. Pass the OFDM modulated data through the AWGN channel and then apply OFDM demodulation. Demodulate the resultant QPSK data and compare it with the original data to determine the symbol error rate.
