Embodiment Construction

[0052] figure 1 An embodiment of a wireless transmitter 100 communicating with a wireless receiver 110 over a channel 120 is shown. The receiver 110 includes a baseband processor 130 . Various signal processing modules are included in or associated with the baseband processor 130 . The signal processing module is configured to operatively execute various functions or algorithms based on parameters input to the module, enabling the receiver 110 to function properly. The one or more signal processing modules are configured to be operatively configured based on the geometry factor and the variance of the geometry factor determined for the channel 120 transmitting the signal to the receiver 110 . Signals may be sent to receiver 110 in an uplink direction (ie, mobile station to base station) or a downlink direction (ie, base station to mobile station). In either case, the geometry factor may be a measure of interference (other / inter-cell interference) and noise (impairment) from...

Abstract

This disclosure is directed to a wireless receiver and a method for configuring the wireless receiver, comprising the actions of determining a geometry factor for a channel over which signals are transmitted to the wireless receiver, the geometry factor being a measure indicative of inter-cell interference plus noise power at the wireless receiver; determining the variance of the determined geometry factor, the variance being a measure indicative of the variation in time or rate of the geometry factor; and configuring the wireless receiver based on the geometry factor and the variance of the geometry factor.

Description

technical field [0001] The present invention relates generally to configurable wireless receivers, and more particularly to configuring wireless receivers based on estimates of channel geometry. Background technique [0002] In a WCDMA (Wideband CDMA) system, a wireless receiver must efficiently demodulate and decode data under a variety of operating conditions. Some of the operating conditions that affect receiver performance include: channel dispersion, receiver speed, and channel geometry (transmitter power to cumulative interference-plus-noise power ratio). Ideally, a wireless receiver should achieve the best possible performance given the operating conditions. One way to maximize performance is to fix the receiver configuration. Alternatively, the receiver can detect operating conditions and reconfigure itself (adaptive configuration). [0003] In order to obtain the best possible performance under given operating conditions, fixed configuration receivers must be des...
