On the orthogonal designs of order 24
Using a new method, all 18 remaining full orthogonal designs of order 24 in four variables (unsolved for more than 20 years) are constructed. The last three remaining orthogonal designs of order 24 in three variables are obtained as a special case of three of these designs.

Orthogonal Designs and a Cubic Binary Function [PDF]
Orthogonal designs are fundamental mathematical notions used in the construction of space time block codes for wireless transmissions. Designs have two important parameters, the rate and the decoding delay; the main problem of the theory is to construct designs maximizing the rate and minimizing the decoding delay.
