MIMO-OFDM Precoding with Phased Arrays

How phased arrays are used in a MIMO-OFDM communication system employing beamforming. Using components from Communications Toolbox™ and Phased Array System Toolbox™, it models the radiating elements that comprise a transmitter and the front-end receiver components, for a MIMO-OFDM communication system. With user-specified parameters, you can validate the performance of the system in terms of bit error rate and constellations for different spatial locations and array sizes.
