Abstract

The local TV broadcast stations operate in the UHF band. These signals are subject to multipath effects in many cases by reflections from buildings and other structures in the broadcasting area. These multipath effects produce delayed signals (ghosts) in the original TV signal. A technique using a smart antenna can be one of the solutions to cancel these multipath signals. A smart antenna is an antenna array system and controller that automatically recognizes desired/undesired signals and adjusts the complex weights of the antenna array to optimize the ratio of the desired to the undesired signals. This paper discusses a small array using a -steering algorithm.
