Study on impact of a multi-antenna DVB-H receiver
on reception performance and
battery power consumption
DVB-H system overview
System modelling for simulation
DVB-H conceptual system overview
DVB-H conceptual system overview (2)
A system model of DVB-H PHY layer has been
developed in the Matlab simulation environment
System simulation model (Matlab) includes
1. DVB-H transmitter
2. MIMO wireless channel
3. Dual antenna DVB-H receiver
DVB-H receiver specifications
Dual stream input
Channel estimation and Equalizer adapted for Maximum Ratio
Maximum Ratio Combining uses a weighted
combination of antenna 1 and antenna 2 signals
High noise impact
High data uncertainty
Assign low weight
Performance comparison between single antenna and
dual antenna DVB-H reception.
Dual antenna reception gives approx. 4 dB performance
gain compared to single antenna.
Dual antenna, MRC Single antenna
~4 dB gain
At 120 km/h, there is a 1.5 dB performance loss
compared to a static channel.
Static 120 km/h
~1.5 dB loss
About 7 to 10% battery power penalty when using dual
antenna reception on typical DVB-H handheld
For dual antenna MRC
2x Front End (FE)
1.5x Baseband (BB)
Approx. 7% increase in
Standard compliant DVB-H model has been developed
Dual antenna DVB-H reception has been simulated
With a typical channel, approx. 4 dB gain is achieved in
receiver performance (before MPE-FEC)…
… and gives an increase of about 7% in battery power
consumption on general DVB-H handheld.
