ADJACENT AND CO-CHANNEL INTERFERENCE DISTURBANCES FROM A DIGITAL TERRESTRIAL TELEVISION SIGNAL(COFDM-8K System) ON ANALOGUE PAL SYSTEMS
نویسندگان
چکیده
This paper presents some early results from a measurement campaign in the service area of the digital terrestrial television (COFDM-8K system) experimental network of Madrid (Spain). The purpose of this survey has been to determine the degradation suffered by analogue PAL-G signals in presence of co-channel and adjacent channel digital emissions. The result from this study is a curve that estimates the protection ratios between analogue and digital received power levels.

DVB-T BER measurements in the presence of adjacent channel and co-channel analogue television interference
This paper presents some laboratory tests carried out to measure the BER degradation caused by an analogue PAL-G television interference on a COFDM 8K digital television signal. The tests made include co-channel and both upper and lower adjacent channel interference situations. Recently this year, the ITU-R has presented some protection ratios to be sought when planning DVB-T networks. The resu...
