Multiple polarization communications

Abstract

If two independent signals are com orthogonal polarizations, the communication thro compared to a single polarization. Polarization re two independent signals in the same bandwidth an attention to obtain adequate isolation between th cochannel interference. Polarization reuse is li the communication throughput because any pola one orthogonal polarization. A new technique u orthogonal polarizations and signal processin separate and combine multiple signal componen than double the communication throughput.

Optimal Antenna Angles for Data Transmission Systems Using Multiple Linear Polarized Antennas

“…기존연구에서는 직교편파뿐만 아니라 더 많은 편파 를 이용해 세 개 이상의 데이터 스트림을 전송하였다 [2] . 그러나 LoS 환경에서 두 개 이상의 데이터 스트림 을 전송할 때 랭크가 2인 무선채널을 통해 2보다 큰 수 의 독립적인 데이터를 전송하므로 큰 성능열화가 발생 한다 [3,4] .…”

Capacity Enhancement of 5G 4T4R network using multiple non orthogonal polarization antenna system with transmitter beam angular diversity

“…There are limited studies on utilization of multiple pol (more than 2). A proposal of using multiple pol scheme is presented in [8] for capacity improvement using signal processing technique with a priori information for an individual pol signal identification. The proposal describe method to use multi-pol signal and its detection but there are no analysis result in that paper.…”

Utilizing Non-Orthogonal Polarization With Polarization Reuse Technique for 4 × 4 MIMO Capacity Enhancement

“…A further increase in the MIMO capacity could be expected with greater number of polarization signal (more than two polarization). Such schemes were proposed and tested in [21], [22], however, multiple polarization channel could not be orthogonal to each other and therefore could have high correlation, which will severely degrade the channel capacity. A signal separation algorithm using priory signal information is suggested in [21] to use multiple polarization communication.…”

In the literature, there are very few studies on the use of more than 2 polarization in MIMO system.…”
