The method of optimal transmission of binary communication without intersymbolic interference, taking into account space-time coding by Alamouty
The system of transmission of data with multi-frequency modulation and optimal finite signals that do not cause inter-symbolic interference in the communication channel is investigated. A new structure of the optimal coherent modem has been developed for each individual channel of the system. In order to improve the spectral efficiency of the system, a three-stage model of orthogonization of canal signals has been introduced. To improve the energy efficiency of the system in channel modems implemented the method of space-time coding on Alamouty. Analysis of the spectral-energy efficiency of the system shows the advantage of the new scheme of organization of channel modems compared to known modern modems.
