要約

The principles of a signal-code sequence shaping are considered, the means and new technologies for selection of the type of the signal sequence are suggested in order to attain the best throughput and efficiency parameters in the telecommunication channel of a wireless data transmission system where the performance is determined by the signal-to-noise ratio at the input of the receiver. Based on the analysis of parameters and criteria recommended by IEEE 802.11a/n specifications for selection of the signal-code sequences, it is suggested the informational efficiency parameter for using the telecommunication channel resources.
The telecommunication line was tested to the range of 1.7 km with the help of MikroTik R52n-M wireless interfaces. There were defined the signal-code sequences, which were selected for data transmission by the software-defined radio systems. It was determined that judging upon the signal level at the input of the receiver, types of the signal-code sequence and the obtained data transmission rate, the software-defined radio system using the MikroTik R52n-M equipment is fully compliant with the recommendations provided in IEEE 802.11a/n specifications.
Realization of the concept for creation of a Wi-Fi-based software-defined radio systems is demonstrated on the example of a developed gigabit data transmission system in the 130...134 GHz bandwidth of the terahertz band. The system was tested in vitro where it attained the data transmission rate of up to 1.2 Gbps. It is demonstrated that the above data transmission system can be potentially used in transportation and distribution networks for the next generation mobile communication networks providing for the required bitrate, reliability and protection.
