This project proposed a novel technology to optimize the assignment of subcarrier set and the number of access point clusters and improve the communication quality of different networks.

A technique known as multicarrier-division duplex (MDD) allows a receiver in the network to be nearly free of self-interference in the digital domain by relying only on fast Fourier transform (FFT) processing.

Computer scientists at the U.K.'s University of Leicester developed a technique to manage mobile network demand by multiple Internet of Things (IoT) devices using terahertz frequencies.

The multicarrier-division duplex (MDD) technique uses fast Fourier transform (FFT) processing to virtually eliminate self-interference among network receivers in the digital domain.

The technology optimizes subcarrier set assignment and the number of access point clusters to enhance communication quality.

Simulations based on real-world industrial settings demonstrated that the new technique outperforms existing technologies while reducing power consumption by 10%.

Said the University of Leicester's Huiyu Zhou, "With our proposed technology, 5G/6G systems require less energy consumption, have faster device selection, and less resource allocation. Users may feel their mobile communication is quicker, wider, and with reduced power demands."
