Prototype of High-Speed Data Transmission Receiving and Transmitting Equipment in the 57‒64 GHz Frequency Range

The purpose of this work is to create and study the characteristics of a prototype of receiving and transmitting equipment operating in the millimeter wavelength range in high-speed data transmission networks. During the work, the task of developing and software implementation of digital signal processing algorithms was solved, the hardware part was developed and implemented, experimental measurements of characteristics and field tests of the prototype were carried out. Experimental studies have shown that the developed equipment transmits and receives signals in the frequency range 57‒64 GHz with the possibility of discrete change of the signal frequency bandwidth: 100, 200, 400, 800 MHz and supports 12 modulation and coding schemes with low-density parity check code. The use of an adaptive algorithm for demodulation and decoding at the receiver made it possible to increase the efficiency of signal transmission and reduce the probability of packet errors by half. The developed prototype provides a data transmission rate of 2 Gbit/s at distances up to 100 m and of 500 Mbit/s at distances up to 300 m.
