... standard tableau, it maps it to an x -standard tableaux with the relation µ(N a T )= type (2 a 1 b ) (T )forT ∈ST 2a+ b . This operator is a bijection between standard tableaux and x -standard tableaux ... gives an algorithm for ’building’ the standard tableaux of size n + 2 from the standard tableaux of size n and divides the standard tableaux i...

... symbols. A subset of this matrix can be used for systems that are smaller than 4 × 4. This matrix pattern can also be extended to accommodate systems with more antennas. P = ⎡ ⎢ ⎢ ⎣ a −aa a aa−aa aaa a −aaaa ⎤ ⎥ ⎥ ⎦ (16) In ... 2 and 3 TX antenna cases. We can see the gains for the two-stage approach are consistent across the entire SIR range. We also notice that the SMI...
