Physical Layer DVB Transmission Optimisation

Projektbeschreibung


Broadband for all

The objective of this project is to research and develop novel techniques for broadcast transmitter networks that will minimise the complexity and power consumption of end user equipment. These techniques; Transmitter Diversity and Low Cost On-Channel Repeaters will improve reception in areas of poor coverage such as for mobile reception, indoors and sparsely populated or obscured locations. Test service scenarios will be developed to illustrate the benefits of the technology so that effectiveness can be researched in a variety of service and terrain scenarios using purpose built test systems.DVB-T DVB-H, DAB are key radio broadcast network technologies which are expected to complement emerging technologies such as WiMAX and its derivatives in future 4G networks. These technologies use Orthogonal Frequency Division Multiplexing (OFDM), which is a technique that distributes data over a large number of carriers spaced apart at precise frequencies providing frequency diversity. Complexity and power consumption of personal receiving devices can be optimised by improving the transmission of signals in non line of sight cluttered environments using Transmit Diversity and Low Cost Repeaters. Transmit Diversity exploits the statistical nature of fading due to multipaths. Resultant digital broadcast networks would have fewer transmitter sites and thus be more cost-effective and have less environmental impact. Transmit Diversity is more practical than Receive Diversity due to the difficulty of locating two receive antennas far enough apart in a small mobile device.Currently in-fill transmitters are used to illuminate ¿black holes¿ where network broadcast signals cannot penetrate. These transmitters generally use different polarisations and frequency channels to the main transmitters. Low Cost on-frequency transmitters, although technically demanding could provide a better way of illuminating ¿black holes¿ with minimal complexity and conserving valuable spectrum.
