Influence of mobile network interfering products on DVB-T/H broadcasting services

Abstract

Abstract-In this paper the influence of mobile network interfering products on DTV (Digital Television) services is explored and evaluated. More precisely, the overall aim of this paper is to measure and show the interactions between the mobile (GSM) and digital terrestrial television (DVB-T/H) broadcasting networks and services. In the DVB-T/H system configuration, the TPS (Transmission Parameter Signaling) carriers keep the receiver informed about the main system parameters. Disturbance of these carriers by interfering products of GSM network and degradation of DVB-T services are also explored and described. Theoretical backgrounds, general workplace and the principle of the measuring method is also introduced and briefly described. For the evaluation of the impact of mobile networks on the signal quality of DTV services the BER (Bit Error Ratio), MER (Modulation Error Ratio) ratios and constellation imperfections are used. Finally, the obtained results are evaluated and clearly described.

Interference Analysis between Mobile Radio and Digital Terrestrial Television in the Digital Dividend Spectrum

“…After theoretical analysis and simulations, in order to measure the impact of the interfering LTE system on the DVB-T system, appropriate experimental laboratory test beds have been used and results have been presented in [17][18][19][20][21][22][23]. Results from laboratory and conducted field tests cannot be directly compared, due to different DTT standard and LTE parametrization used in those tests.…”

“…For example, high dependence of the digital TV signal power to interfering signal power ratio on the bandwidth of the interfering signal and applied FEC protection has been measured in [18]. However, significant PR value offset between channel 60, and channels 58-59 has been confirmed, both in laboratory [17][18][19][20][21][22][23] and conducted field test.…”

“…Taking into account the power density spectrum load dependency of an eNodeB signal, the present paper aims to provide an effective contribution in the comparison of the PR and PD results obtained from the field measurements with results obtained from the simulations [12][13][14], and results obtained from laboratory measurements [17][18][19][20][21][22][23].…”

Co-channel coexistence between DVB-T/H and LTE standards in a shared frequency band

“…Nowadays, the attention in this field is more focused on the study of coexistence scenarios between DVB-T/H and LTE systems. General interaction between mobile telecommunication and DTV services is studied in [8]. Authors in [9] and [10], focused on the exploring of possible adjacent channel interference of the LTE mobile system (at downlink) into DVB-T services at fixed reception scenario.…”

Study of the coexistence between ZigBee and Wi-Fi IEEE 802.11b/g networks in the ISM band

“…The risk of coexistences or nascent adjacent channel interferences between different wireless systems can negatively affect the quality of their provided services [1]- [3]. Exact measurements and monitoring of the performance degradation of coexisting systems are becoming one of the most important issues.…”
