A pilot-aided rake receiver suitable for CDMA wireless telecommunications is disclosed. Some rake receivers in accordance with the present invention require fewer computational resources to be consumed by the conjugate pilot estimate multipliers than some pilot-aided rake receivers in the prior art. One embodiment of the present invention comprises: N rake receiver fingers, wherein each of the N rake receiver fingers outputs an information-bearing signal, Ii(n), and a conjugate pilot estimate, Pi(n); N multipliers; and an N x N switch interposed between the N rake receivers and the N multipliers for routing the information-bearing signal, Ii(n), and the conjugate pilot estimate, Pi(n), from any of the N rake receiver fingers to any of the N multipliers. In some embodiments of the present invention, the N multipliers are pooled and shared by the resources (e.g., rake receiver fingers, coheren t combiners, etc.) associated with a plurality of users.
