Abstract
Apparatus and method to process a pilot channel and a synchronization channel to obtain a combined noise estimate of the pilot channel and the synchronization channel that is synchronized to the pilot channel. The combined noise estimation is processed to determine a first noise component for a period when both the pilot channel and the synchronization channel are present. Then, the combined noise estimate is processed to determine a second noise component for a period when only the pilot channel is present. Next, the second noise component is subtracted from the first noise component to derive a noise estimation for the synchronization channel. The technique may be applied to the Common Pilot Channel (CPICH), and the Synchronization Channel (SCH) defined in a 3rd Generation Partnership Project standard specification.
