Dual Channel MIMO Measurements for WiMAX Wave 2
Benjamin Zarlingo, Agilent Technologies Inc., Everett, Wash.
The WiMAX™ Wave 2 specification now allows the use of multiple antennas for higher system performance in downlink (DL) and uplink (UL) transmissions. For example, systems using multiple input/output (MIMO) configurations can provide higher data rates and greater spectral efficiency than traditional single input/output (SISO) applications. Characterization and troubleshooting of these advanced WiMAX systems often requires a dual channel signal analyzer with channel estimation functionality, a “matrix decoder” and an OFDM demodulator.
