• Short echoes destroy up to 50 of the OFDM
  spectrum, due to small phase variations. These
  short echoes need to be compensated by reception
  with at least 2 antennas, that is, the use of
  diversity.
• DiBcom has implemented diversity for mobile
  reception, it serves dramatically in portable
  situation

21
Mobility and Portability
In PORTABLE reception, the ROBUSTNESS is not
only a matter of sensitivity,
but also of place and time of reception
Space-domain multipath fading Measured with an
omnidirectional antenna Within a small square,
the level can have variations up to 25 dB The
antenna is a key part, it have to cope with these
fadings DIVERSITY is the SOLUTION

3. From DVB-T to DVB-H
23
New The DVB-H approach objectives

• DVB-H New DVB-T based standard since Q4/2002
  to develop broadcast services (including TV) on
  mobile phones
• DVB-H Mobile DVB-T Time Slicing MPE-FEC

DVB-T the constraints to mobility
DVB-H targets
Various modes (16/64 QAM). Most of them reach
high mobility with diversity (2 receivers)
Must be as close as possible to DVB-T Need to
work with single receiver for handheld devices
MPE FEC
Important power consumption due to the high bit
rate received in continuous mode
TIME SLICING (allows a trade-off between power
consumption and the bit rate needed by the
application)
Limited awareness of compatibility with mobile
application/image
Marketing/strong awareness/contribution by large
players

DIB7000 Enhanced DVB-H demodulator ICfor
Handheld environments

• DiB 7000 H IC for DVB-H
• embed all algorithms of DVB-T IC DiB3000MC
• Additional features for DVB-H
• enhanced FEC MPE-FEC
• Allows a Maximum Doppler compensation (130 Hz)
  in single
• almost as good in a Diversity2 DVB-T without
  MPE-FEC
• - Allows a C/N improvement by around 3 dB at low
  speed
• reduced power consumption TIME SLICING
• - Allows to divide the power consumption of the
  front-end by 10
