Performance Enhancement of ATSC3.0 Using Polarization Property and Frequency Symbol Spreading

Lately, the advanced television systems committee (ATSC) 3.0 standard has been established, enabling the rollout of 4 K ultra-high-definition and simultaneous multichannel high-definition broadcasting services. A unique transmitter identification (TxID) sequence is assigned with long spread coding to mitigate interference of the broadcasting signal. In this scenario, the maximum achievable data transmission rate is limited. Currently, to increase the transmission rate of the data signal as a TxID, various researches are being carried out. This paper introduces a new method to reduce interference in data communications using the cross-polarization discrimination (XPD) property. The proposed system can reduce the inference from both of the broadcasting signal and TxID signal using polarization property. Therefore, the proposed system can enhance the data transmission rates without causing the interference to the broadcasting signal.
