ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to wireless communication systems and, in particular, to signal improvement for such wireless communication systems.
BACKGROUND OF THE INVENTION
Often times an operator of a wireless remote unit cannot adequately configure the remote unit to provide an acceptable quality level for a received signal. For example, many remote unit subscribers operate their remote units permanently at a maximum volume level, and in many cases this level can still be inadequate for a perceived good-quality call. Therefore a need exists for a method and apparatus to improve the quality of a received signal, above and beyond the quality level that is capable of being achieved by the wireless remote unit alone.
