WiMAX Signal Analysis Part 1: Time and Frequency Measurements
Applikationsberichte
This application note is intended for engineers that are familiar with the IEEE 802.16-2004 (WiMAX) physical layer standard and wish to improve their measurement understanding and capabilities using a vector signal analyzer. This note will provide information on how to improve WiMAX signal analysis and includes measurement tips when designing and troubleshooting a new or an existing product. In order for the RF engineer to successfully test and troubleshoot a WiMAX device, a well-organized approach to the signal analysis will yield the greatest level of understanding and reliability in the measurement. This application note from Keysight Technologies, Inc. is the irst part in a three note series that provide the framework for the preferred measurement approach that includes frequency and time measurements, digital demodulation and analysis of the advanced functionality within the WiMAX physical layer deinition. If you are familiar with the 802.16-2004 standard but not necessarily familiar with WiMAX measurements, you may ind reading all the application notes in this series very useful for expanding your knowledge of testing and troubleshooting this complex signal. For the engineer that is relatively new to the 802.16-2004 standard, a brief review of the standard will be provided, which includes many technical references for those wishing to gain additional background into the IEEE standard and OFDM structure of the WiMAX physical layer.
