摘要： Digital calculation of an RSSI value begins by digitally calculating a magnitude of a signal (e.g., a received RF signal or representation thereof). The process then continues by filtering the magnitude of the signal to produce a filtered magnitude signal. The process then continues by determining a coarse RSSI value of the filtered magnitude signal, wherein the coarse RSSI value indicates a sliding window of RSSI values. Once the coarse RSSI value is obtained, the process continues by determining a fine RSSI value within the sliding window of RSSI values. The process concludes by summing the fine RSSI value with the coarse RSSI value to produce a digital RSSI value.

摘要： Hybrid location determination for wireless communication device. Various services that may be used by a wireless communication device within a particular location may be referred to as location based services (LBS). As such, means by which the location of a wireless communication device that may use such available services, within such a locale, is made by using more than one type of location determination approach. For example, a wireless communication device includes communication capability (e.g., RX and TX) in accordance with a first communication protocol (e.g., Bluetooth) and also includes a communication capability (e.g., RX only) in accordance with a second communication protocol (e.g., WiFi/WLAN (Wireless Local Area Network)). The RX capability is operative to assist in location determination for the wireless communication device based on knowledge of at least one wireless communication device that communicates with the wireless communication device.

摘要： A method for calibrating a filter begins with the filter filtering a first signal having a first frequency to produce a first filtered signal, wherein the first frequency is in a known pass region of the filter. The processing continues by measuring signal strength of the first filtered signal to produce a first measured signal strength. The processing continues with the filter filtering a second signal having a second frequency to produce a second filtered signal, wherein the second frequency is at a desired corner frequency of the filter. The processing continues by measuring signal strength of the second filtered signal to produce a second measured signal strength. The processing continues by comparing the first measured signal strength with the second measured signal strength to determine whether the filter has attenuated the second signal by a desired attenuation value with respect to the first signal. The processing continues by adjusting filter response of the filter to produce an adjusted filter response when the filter has not attenuated the second signal by the desired attenuation value with respect to the first signal.
摘要翻译： 用于校准滤波器的方法开始于对具有第一频率的第一信号进行滤波，以产生第一滤波信号，其中第一频率在滤波器的已知通过区域中。 通过测量第一滤波信号的信号强度以产生第一测量信号强度，继续处理。 处理继续，滤波器对具有第二频率的第二信号进行滤波以产生第二滤波信号，其中第二频率处于滤波器的期望转角频率。 该处理通过测量第二滤波信号的信号强度继续，以产生第二测量信号强度。 该处理通过将第一测量信号强度与第二测量信号强度进行比较来确定滤波器是否已经相对于第一信号衰减了所需的衰减值来衰减第二信号。 当滤波器没有相对于第一信号衰减所需的衰减值时，滤波器的滤波器响应通过调节滤波器的滤波器响应来产生经调整的滤波器响应，从而继续该处理。

摘要： A method for adjusting automatic gain control of a radio receiver begins by determining power level of a radio frequency (RF) signal received by the radio receiver to produce a determined power level. The method then continues by comparing the determined power level with a plurality of power thresholds to determine whether an automatic gain adjustment is needed. The method then continues, when the automatic gain adjustment is needed, by determining, from the comparing the determined power level with the plurality of power thresholds, a sign of the automatic gain adjustment. The method continues by determining, from the comparing the determined power level with the plurality of power thresholds, a magnitude of the automatic gain adjustment. The method continues by addressing a gain adjustment look up table for at least a portion of the radio receiver based on the magnitude to produce a gain setting. The method then continues by adjusting the automatic gain of the radio receiver based on the sign of the automatic gain adjustment and the gain setting.
