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.

Wireless communication device and method for communicating in site selection diversity mode

Apparatuses, methods, and articles of manufacture disclosing a filter with a plurality of convolver branches are described herein. Each of the plurality of convolver branches include a multiplier, integrator, and sampler and hold circuit. A sampled output of one branch may be fed back to another branch. Other embodiments may be described and claimed.

Programmable filter

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.

Metric correction for multi user detection, for long codes DS-CDMA

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.

Device, systems, and methods to detect unknown transmission formats are provided. Viterbi metric values may be calculated for a plurality of possible format parameters for a transmission format. Format metric values may be calculated for a plurality of the calculated Viterbi metric values, and the calculated format metric values may be compared. Based on the comparison, a probable transmitted format from a set of possible formats may be determined.

Device, system and method for blind format detection

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.
