Signal transmitting/receiving apparatus and method for controlling polarization

Abstract

Disclosed are signal transmitting apparatus and method capable of generating polarizations that can be controlled in real time by allocating weights to signals. A signal transmitting method for generating variable polarizations having any vector through a plurality of radiating elements vertical to each other includes: receiving an input signal and separating the input signal into a plurality of separated signals according to the number of radiating elements; and allocating weights for controlling vectors of the variable polarizations to each of the plurality of separated signals, wherein the vectors of the variable polarizations are represented by a vector sum of the plurality of separated signals allocated with weights.

AI Technical Summary

Benefits of technology

This approach enhances wireless communication quality, increases traffic capacity, and adapts to various services by generating variable polarizations, thereby overcoming limitations in frequency resource management and improving service quality in diverse propagation environments.

Problems solved by technology

Types and usage of wireless communication services have been continuously increased and frequency resources that are the most important resources in wireless communications has been depleted accordingly.

However, an antenna of a communication terminal or a repeater / base station of most of the MIMO communications uses an antenna system having fixed variable polarizations and therefore, is difficult to cope with the degradation in communication quality occurring at the time of inter-service interference due to the expansion and broadband of service.

In addition, the antenna system in accordance with the related art has a limitation in overcoming the lack of the frequency resources.
