草议IEEE802.11n 测量解决方案和多输入多输出(MIMO)测量挑战

The IEEE802.11n is the evolution of existing IEEE802.11a/b/g system and promises to have enhanced data rates, better spectral efficiency, better quality and a more robust system. This application fact sheet provides an overview of Tektronix's measurement solution of Draft 802.11n Multiple Input Multiple Output (MIMO) with the Real time Spectrum analyzer (RTSA). In a MIMO system, one must consider the characteristics of the multipath fading channel and propagation characteristics of transmission in addition to measuring a single transmitter's performance at the antenna connector.
