Orthogonal Designs With Maximal Rates

Orthogonal designs have been used as space–time block codes for wireless communications with multiple transmit
antennas, which can achieve full transmit diversity and have a very simple decoupled maximum-likelihood decoding algorithm.
The rate of an orthogonal design is defined as the ratio of the
number of transmitted information symbols in a block of channel uses to the length of the given block, which reflects the bandwidth efficiency of the employed space–time block code constructed from the orthogonal design.
This code simulates and synthesis an orthogonal
matrix code with the maximum possible rate.attached is the related article.
