Rohde & Schwarz offers a complete test solution for WiMAX applications by combining its Signal Generator R&S SMU200A and Signal Analyzer R&S FSQ and adding the appropriate options. This application note provides an overview of the differences between OFDM (Orthogonal Frequency Division Multiplexing) and OFDMA (Orthogonal Frequency Division Multiple Access), and demonstrates how convenient it is to generate and analyze WiMAX OFDMA signals according to standard IEEE 802.16e-2005.
