摘要:
Aspects of a method and system for using a wireless local area network (WLAN) phase shifter for smart antenna beam steering are presented. Aspects of the system may enable determination of an angle of arrival (AOA) for signals received at a receiving station in a wireless network. Based on the AOA value, the receiving station may enable orientation of antenna in a smart antenna system. In a switched beam smart antenna system, antenna element(s) may be selected, which are most closely oriented toward the AOA. In an adaptive array smart antenna system, antenna beam may be steered, or reoriented, based on the AOA.

An integrated circuit (IC) includes a clock circuit, a processing module, and processing circuitry. The clock circuit is coupled to produce a digital clock signal. The processing module is coupled to determine whether a harmonic component of the digital clock signal having a nominal digital clock rate is within the frequency passband and to provide an indication to the clock circuit to adjust its rate from the nominal digital clock rate to an adjusted digital clock rate when the harmonic component of the digital clock signal is within the frequency passband. The processing circuitry is coupled to process, at the adjusted digital clock rate, the data to produce processed data having a rate corresponding to the nominal digital clock rate and to interpolate, at an interpolation rate, the processed data to produce interpolated processed data having a rate corresponding to the interpolation rate.
摘要:
A modem includes a Digital Access Arrangement (DAA) Circuit and modem software that is executed by a processor. When the DAA Circuit detects that the modem software is nonfunctional, it enters an on-hook state to prevent blocking of a coupled telephone line. A nonfunctional state of the modem software is detected when the modem software ceases to interact with the DAA Circuit in an expected manner. In a first operation, the nonfunctional state is determined when the modem software does not reset a count down timer in the DAA Circuit before the count down timer reaches a termination value. In a second operation, the nonfunctional state is determined when the modem software does not access the DAA Circuit before the count down timer reaches the termination value. In a third operation, the nonfunctional state is determined when the modem software ceases writing transmit data to DMA memory.
摘要:
A type or brand of remote communication device is identified by measuring one or more characteristics associated with one or more signals sent by the remote communication device. The measured characteristics differ among different devices and/or manufacturers and are compared to known characteristics of one or more signals associated with known communication devices. Once the remote communication device is identified, the local communication device can enable one or more performance enhancing or deficiency compensation features based on the identity of the remote communication device.
