20 October 2006 10 Benefits of DiBcom “Proven Performance” DVB-H receivers

DiB7070-H DiB9080-H (with integrated 2 Silicon Tuner) (7 x7 mm )

Use the “Proven performance “ DVB-H DiBcom receiver DiB707x-H or DiB908x-H with:

 Enhanced C/N : 3 dB better than those of the “Typical Receiver”

 Enhanced Doppler compensation offering 50% more speed than the typical receiver

20 October 2006 11 Proven Performance Advantage: Quality of reception

High Doppler compensation due to:

 channel estimation Doppler bandwidth

 FFT leakage compensation algorithm

 Advanced estimation algorithm to reduce the noise effect on the estimation

Dynamic FFT window positioning:

 Fast track of channel profile variation

 Optimum positioning (no Post / Pre echoes phenomena)

Co-Channel Interference compensation

 Blind algorithm

 Better than MBRAI specification

Impulse noise compensation

 Very robust even in mobile environment

20 October 2006 26 CONCLUSION

DVB-H is the world’s most efficient standard for Mobile TV applications DVB-H receiver compliance is not sufficient Small differences in DVB-H receiver quality (Sensitivity, Doppler compensation,..) can have enormous consequences when it comes to:  Network Quality (especially coverage)  and cost ! The “Proven Performance” receiver also known as the “Possible Reference Receiver” (DVB-H Implementation Guidelines) is becoming a “de facto” standard thanks to the world’s first DVB-H commercial launch in Italy.
