Abstract

The DTV receiver and its antenna are viewed as a receiving system and it is improvements to this receiving system which are addressed. It appears possible to improve the signal-strength problem primarily with improvements in the antenna part of the system by means of a low noise preamplifier at the antenna, (active directional antennas) and to improve the multipath handling within the receiver. Improved receiver tuner design can also deal with the field strength problem. Adaptive antennas for diversity reception can also contribute to solving the multipath problems as shown.
