New Transmitter/Receiver Diversity Scheme in DVB-H systems over Outdoor and Indoor Environments

The objective of this paper is to research and develop novel diversity techniques for broadcast transmitter networks that will minimise the complexity and power consumption of end user equipment. Transmitter Diversity will improve reception in areas of poor coverage such as for mobile reception, indoors and sparsely populated or obscured locations. Rapid development in the area of broadband wireless communications demands wireless multimedia services. One of the challenges of transmitting multimedia over wireless channels is that fading and interference can severely deteriorate the received signals. Orthogonal Frequency Division Multiplexing (OFDM) is a suitable technique for broadban
