System and mehtod for providing an accurate estimation of received signal interference for use in wireless communication systems

摘要

An code division multiple access (CDMA) communication apparatus (66) in which the apparatus (66) is arranged to receive (14, 56) a signal over a wireless channel, the received signal including a desired signal component and an interference component. The apparatus (66) is arranged to estimate (12) the carrier signal-to-interference and interference energy of the received signal to generate an interference energy value and a signal-to-interference ratio of the received signal, where estimating carrier signal-to-interference and interference energy includes extracting an estimate of the desired signal component from the received signal. The apparatus (66) is further arranged for generating summed weighted-path signals (42) in response to the interference energy value and the estimate of the desired signal component.
