Abstract: 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.

Abstract: A receiver in a wireless communication system utilizes a metric to minimize the error probability in transmitted information. The receiver may use a detector utilizing multiuser detection or rake detection. The output symbols of the detector are examined and a metric is obtained related to the noise and interference that may have distorted the transmission of the symbol. This metric is supplied to a channel decoder along with the symbol to improve decoding.

Abstract: Briefly, in accordance with one embodiment of the invention, a programmable filter may implement an infinite impulse response filter so that a transceiver in which the filter is utilized may be programmable to operate in one or more modes in accordance with one or more communication standards. The programmable infinite impulse response filter may replace one or more analog filters of the transceiver so that a desired filter response may be programmed by a baseband processor. Delay functions of an infinite impulse response filter may be implemented using feedback and multiplexing.

Abstract: 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 least 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 of each of a set of possible directions of joint movement of the fingers of the finger block, selecting one of the direction metrics according to a predetermined criterion, and moving the fingers of the finger block in the directions indicated by the selected direction metric.

Abstract: A wideband CDMA searcher and method accelerate searching for signal paths of a spread-spectrum signal. I and Q components of a received signal may be sampled at approximately once per chip and summed over one or more symbols to determine a measured channel value at a specific delay. The delay between sequentially checked paths may be one chip or less. A channel value may be estimated for each delay of the spreading code based in the measured channel values. A signal path may be selected based on the channel value for use in subsequent signal tracking.
