RF Engineering, Implementation, and Operation
There are so many topics to cover when we consider Multiple Input Multiple Output (MIMO) that we will have to narrow the focus to get anywhere. MIMO requires good diversity! How much depends on the frequency and distance from the transmission. There are ways to improve diversity and it has to do with Phase shift. LTE is a robust broadband with excellent forward error correction (FEC) built in. It also has the added feature of scheduling energy only into the Resource Blocks (RB) that are in the best RF conditions. I know it sounds scifi, but I've seen this phenomenon while testing on Ericsson's eNode B in Sprints Lab. The LTE Channel energizes consistently on the RBs that have the best SINR. This is easily provable with the right test setup.
This is where you can get answers to your toughest technical questions. Use our community of experts to test your theories and get advice from those who have been there and done that. =)
The goal is to make a lot of friends while asking questions and sharing information not misinformation. We respect all thought and points of view, we recommend sticking to RF theory, Standards and what’s provable by math, and require 99.9% civil conduct and proper manners at ALL times, because nobody is 100% right or perfect.
No other rules for now.
