Space-Time Coding
Space-time coding (STC) is a technique for implementing transmission diversity. Mobile
WiMAX uses transmit diversity in the downlink direction to provide spatial diversity that
enhances the signal quality to a specific subscriber located anywhere within the range of the
antenna beam. Although providing less signal gain than beam-forming, transmit diversity is
more robust for mobile users since it does not require prior knowledge of the path
