Hello
Alamouti scheme (amongst others) is said to be an orthogonal STBC. What I don't understand is the "orthogonal" part. WHAT exactly is orthogonal? Can somebody show me mathematically how it is orthogonal? I've tried using the orthogonal matrix definition (matrix times its transpose = identity matrix) with no luck.
