The diagrams below show the different techniques that can be used with MIMO in an 802.11n and 802.11ac system, when the client has a multiple antennas or a single antenna. In the following section we will briefly explain each technique. Cyclic shift diversity (CSD) Sometimes called cyclic dela...
Pilot insertion and cyclic shift diversity (CSD). Constellation points for transmission are combined with the data for pilot subcarriers to create the complete data set for transmission. When multiple data streams are present, they are each given a small phase shift to aid in distinguishing between...
