前言: MIMO 一直是NR,LTE,WIFI 里面最核心,最复杂的技术之一.
这个系列大概花两个月时间,探索一下MIMO. 每次大概10分钟左右的课程. 这篇主要参考Ahmed Farhan Hanif 7年前的一篇科普文章 MIMO and Beamforming in Wireless Systems (4G, 5G…

Intelligent Reflecting Surface Enhanced Wireless Network via Joint Active and Passive Beamforming
该文章主要针对IRS通信网络进行beamforming设计 与其类似的短文还有 Intelligent Reflecting Surface Enhanced Wireless Network: Joint Active and Passive Beamformin…
简介
Beamforming,即波束成形,是一种让信号能量集中在一个方向上的传输技术。
规范 802.11n (wifi-4) defined several methods for beamforming,optional;802.11ac (wifi-5) settled on a standard NDP method;802.11ax (wifi-6) will bring uplink MU-MIMO, this does…
前言: Beamforming 是MIMO 技术里面的核心技术之一,所以讲MIMO 必须对Beamforming
有所了解,本篇主要了解一下beamforming Explains how a beam is formed by adding delays to antenna elements. 波束赋形(Beamformingÿ…

1. 阵列简介
1.1 均匀线阵 假设0、1、…M-1阵元的均匀线阵中,参考阵元接收的信号为 s ( t ) s(t) s(t),则第 m m m个阵元接收到的信号为 s ( t − τ m ) s(t-\tau_m) s(t−τm),傅里叶变换如下 S m ( ω ) ∫ − ∞ ∞ s m ( t ) e − …
Beamforming enables you to find problems in your system before they occur. As Martin explains, you can perform your own investigation with a computer, a dual-channel A/D card, a pair of microphones, and some software. Tensions are high and a hostile su…
