Method and apparatus for adaptive noise and/or signal filtering in an hsdpa channel quality indicator (cqi) selection

Abstract

Methods and systems for processing signals in a wireless communication system are disclosed. Aspects of the method may include estimating at a receiver, a rate at which a communication channel changes. A length of a filter used to average a noise power estimate and/or a signal power estimate may be adaptively changed based on the estimation of the rate at which the communication channel changes. The communication channel may comprise a common pilot channel (CPICH). At least a portion of a wireless signal received via the communication channel may be descrambled at the receiver to generate a plurality of descrambled bits. At least a portion of the plurality of descrambled bits may be accumulated to generate at least one in-phase (I) component and at least one quadrature (Q) component.

         21 . A method for processing signals in a wireless communication system, the method comprising:
 performing by one or more processors and/or circuits integrated within a single chip:
 estimating at a receiver, a rate at which a communication channel changes; and 
 adaptively changing a length of a filter used to average one or both of: a noise power estimate and a signal amplitude estimate, based on said estimation of said rate at which said communication channel changes.
