| 1. An apparatus comprising:
a quality measurement circuit;
a power control processor configured to tune to a first frequency during an initial portion of a first frame, to tune to a
second frequency during a period that begins during the first frame and continues through an initial portion of a second frame,
wherein the second frame follows immediately after the first frame, to direct the quality measurement circuit to measure at
least one signal attribute on the second frequency during the period, and to tune the receiver on the first frequency during
a remaining portion of the second frame; wherein said power control processor is further configured to increase a target signal
quality over at least a portion of at least one of the first and second frames;
a memory buffer, wherein samples are stored; and
a frequency searcher adapted to simultaneously process said stored samples and said at least one signal received at said first
frequency, wherein no pilot searches and pilot strength measurements are made while on said second frequency.
