WiMAX Depends On Modulation Quality

Sept. 27, 2010

WiMAX broadband wireless communications systems rely on orthogonal-frequency-division-multiplexing (OFDM) techniques for efficient use of available bandwidth. Unfortunately, any efficiency gains with OFDM can be lost as a result of signal distortion. Fortunately, Technical Consultant Bill Wu shows how Matlab/Simulink mathematical modeling software can be used to analyze the effects of signal impairments, such as phase noise, on the modulation quality of single-carrier and multicarrier WiMAX transmitters.
