International audienceThis paper presents a double extension of the mathematical Weyl group with the purpose of increasing the spectral efficiency of the Differential Space-Time Modulation (DSTM) scheme using this group of matrices. The error performance of the system is improved through an optimal selection of the matrices selected for a given spectral efficiency and an optimal mapping between the binary data vectors and the information matrices. Finally, the performance of the obtained system is evaluated using a more realistic time-varying channel model
