ABSTRACT:
Objective reception quality assessment is the process to quantitatively evaluate the reception quality based on field measurements. The assessment of digital terrestrial television broadcasting signals is very useful, as it provides fundamental information towards government decision on policy settings for digital switchover. Previous assessments defined by International Telecommunication Union (ITU) are based on the combined parameters of field strength, bit error rate before and after Viterbi decoder, which are not always available in field measurement and in complex broadcasting environment such as Single-Frequency Network(SFN). Based on the statistical analysis of more than 30,000 digital television measurement data, a new objective reception quality assessment method is presented. This method mainly focuses on field strength and modulation error ratio. Therefore, a quick and convenient indication on reception quality is available. Trials on measurement data shows the results obtained from this new method align very well with the ones by ITU. Besides, some quantitative relationships between measurement parameters in Digital Video Broadcasting a" Terrestrial (DVB-T) standard are presented.
BIO:
Weiyu Huang is currently an honours year R&D undergraduate student, majoring in Electronics and Telecommunications. He has completed several projects in the areas of organ segmentation, acceleration based on parallel computation, and photoacoustic image reconstruction. He was responsible to evaluate the risk of interference under the band edge sharing scenario of DVB-T and LTE in Australian digital dividend band. Since November 2011, he has been working as a radiofrequency/broadcasting engineer in Australian Communication & Media Authority.
