Description: MATLAB是一个非常好的用于测量，分析和可视化的数据，控制仪器，并建立测试系统。安捷伦信号和频谱分析仪可让您分析失真，虚假的，相位噪声，用于2G到4G无线通信测量。这种Matlab下开发的高级数据可视化（ADV）的应用软件，扩展了安捷伦信号和频谱分析仪的可视化功能，提供了四个不同的显示格式：Analog Advanced, Analog Plus, Waterfall,和Spectrogram。这些显示使得更加容易捕获间歇性信号。-MATLAB is a very good for the measurement, analysis and visualization of data, control apparatus, and to establish test systems. Agilent signal and spectrum analyzers lets you analyze distortion, false, phase noise, for 2G to 4G wireless communication measurements. This developed under Matlab Advanced Data Visualization (ADV) of the application software, the expansion of the Agilent signal and spectrum analyzer visualization capabilities, providing four different display formats: Analog Advanced, Analog Plus, Waterfall, and Spectrogram. These shows make it easier to capture intermittent signals.

Description: The ever growing traffic explosion in mobile
communications has recently drawn increased
attention to the large amount of underutilized
spectrum in the millimeter-wave frequency bands
as a potentially viable solution for achieving tens
to hundreds of times more capacity compared to
current 4G cellular networks. Historically,
mmWave bands were ruled out for cellular usage
mainly due to concerns regarding short-range
and non-line-of-sight coverage issues. In this
article, we present recent results channel
measurement campaigns and the development of
advanced algorithms and a prototype, which
clearly demonstrate that the mmWave band may
indeed be a worthy candidate for next generation (5G) cellular systems-The ever growing traffic explosion in mobile

Description: OFDM技术基本能远离，国外一所大学教授基于MIMO技术讲座的ppt-MIMO systems can exploit multipath components to a certain extent, that is, MIMO can resist multipath fading, but for frequency selective deep fading, the MIMO system is still powerless. At present, the solution to frequency selective fading in MIMO systems is to utilize equalization technology, and another is to use OFDM. Most researchers think that OFDM technology is the core technology of 4G, 4G requires high spectrum utilization of OFDM technology, and improve the spectrum utilization effect is limited, the development of space resources reasonably on the basis of OFDM, which is MIMO+OFDM, can provide higher data transfer rate.
