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. %G English %L hal-02309554 %U https://univ-rennes.hal.science/hal-02309554 %~ UNIV-NANTES %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ IETR %~ STATS-UR1 %~ CENTRALESUPELEC %~ UR1-HAL %~ UR1-MATH-STIC %~ UR1-UFR-ISTIC %~ IETR-SYSCOM %~ IETR-SC %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ TEST-HALCNRS %~ UR1-MATH-NUM %~ NANTES-UNIVERSITE %~ UNIV-NANTES-AV2022
