Matrices analysis based on Jacket for space time block codes

Recently, the orthogonal matrices with correlated values named Jacket were introduced, it can generalize all Walsh Hadamard and weighted Hadamard cases and leads same patterns as space time block codes (STBC). Therefore, in this paper, we analyze the matrices of STBC according to Jacket model, and derive some new cases of quasi-orthogonal matrices to enrich their family. In these cases we use unitary transform according to Jacket model, therefore, they have same diversity gain level. However, some new cases can lead simple correlations canceling based on adjacent transmitted symbols with trade off from code rate before modulations.
