摘要

The detailed network planning of DVB-H requires understanding about the regional differences and their effects on the functionality of the system performance. A deep city center contains various radio components whereas rural area normally consists of a single line-of-sight signal resulting differences in the error behavior in the DVB-H reception. In the city area, the terminal velocity is normally limited to pedestrian and relatively slowly moving vehicular speeds. On the other hand, the Doppler shift might be the limit of DVB-H performance in the motorways across rural areas due to the higher velocities. This paper presents a radio interface quality analysis methodology based on the erroneous frames and bit error rates. A selected set of field and laboratory test cases and respective results of the performance analysis is presented. The results can be used as a basis for balancing the MPE-FEC rate and capacity of DVB-H during the related in-depth radio network optimization.
