Patent ID: 8050237

Claim:
An apparatus comprising: a first symbol processing module coupled to receive a first pre-defined number of symbols of a slot of a downlink common pilot channel that has multiple slots, in which the first symbol processing module accumulates over the first pre-defined number of symbols to obtain a first average noise estimation over the first pre-defined number of symbols for the slot, wherein the first average noise estimation includes noise effects of a synchronization channel that is present during a time period synchronized to the first pre-defined number of symbols; and a second symbol processing module coupled to receive subsequent N number of symbols of the slot following the first pre-defined number of symbols of the slot, in which the second symbol processing module accumulates over the N number of symbols of the slot of the downlink common pilot channel to obtain a second average noise estimation, wherein the second average noise estimation does not include the noise effects of the synchronization channel; and a third processing module to subtract the second average noise estimation from the first average noise estimation to derive a noise estimation for the synchronization channel.
