Several
types of encoding can be used in conjunction with spatial
multiplexing, for instance horizontal encoding and vertical encoding.
V-BLAST (Vertical Bell Labs Layered Space Time Architecture Reference
[1]) is an example of vertical encoding. D-BLAST (Diagonal BLAST
Reference [2]) is a combination of vertical and horizontal encoding
strategies.
