摘要： A wireless communication device receives CDMA signals and communicates with remote base stations in site selection diversity transmit (SSDT) mode. During communications with a primary base station, communication state parameters, such as signal to interference ratio (SIR) target values and carrier frequency estimates, are maintained for other base stations of an active set of base stations. The state parameters for communications with a selected base station are available for use after selection of a new base station. In.one embodiment, the communication state parameters are used for the selection of a base from the active set.

摘要： In a receiver having at least two fingers, the fingers tracking at least one path of a multipath channel, a method includes the steps of forming a finger block of at leat two of the two fingers and jointly tracking the fingers of said finger block. The step of jointly tracking includes the steps of generating direction metrics (12) of each of a set of possible directions of joint movement (16) of the fingers of the finger block, selecting one of the direction metrics (12) according to a predetermined criterion, and moving the fingers of the finger block in the directions indicated by the selected direction metric.
