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.
