摘要:
Provided herein are different embodiments for performing radio frequency interference (RFI) mitigation in electronic devices such as mobile computing systems. In some embodiments, a dynamic RFI mitigation scheme allows for monitoring of wireless channels for RFI and to adaptively shift an identified RFI source (e.g., system clock) harmonics, e.g., either out of the on-channels or to a neutral position within the on-channels such as by using cost-function analysis.
摘要:
A method of sensing radio frequency interference (RFI) in a wireless system is provided. The method includes receiving wireless data through a wireless receiver and evaluating received wireless data through a receiver baseband module to identify an occurrence of a signal detection failure by a physical (PHY) layer or a media access control (MAC) layer of the wireless system. The method also includes triggering a radio frequency interference sensing state in response to the occurrence of signal detection failure by the physical layer or the media access control layer of the wireless system.

A sub-banded ultra-wideband (SB-UWB) system may combine aspects of an orthogonal frequency division multiplexing (OFDM) modulation scheme with aspects of an ultra-wideband system. In one embodiment, the system may use orthogonal waveforms to form an ultra-wideband wireless communications system. In another embodiment, an FFT based implementation of the system may be used to generate and detect an SB-UWB waveform.

Apparatus, system, and method are described for a complementary metal oxide semiconductor (CMOS) integrated circuit device having a first metal layer that includes a radiating element and a second metal layer that includes a first conductor coupled to the radiating element. The first conductor and the radiating element are mutually coupled to form an antenna to wirelessly communicate a signal.

Embodiments include systems and methods for integration of RF components onto a single die with functional processing circuitry. For example, one integrated circuit may comprise multiple processors that can communicate there between by way of Radio Frequency (RF) transmission. The processors may also communicate with slave devices by way of radio frequency. Transmission and reception may be at frequencies in a band hitherto unused in computing devices and their peripherals.

Embodiments include systems and methods for RFI mitigation in a wireless computing environment. In one embodiment, a platform determines RFI information of the platform by listening with a receiver of a transceiver of the platform when the transmitter of the transceiver is quiescent. The platform derives Frequency Domain Weights from the RFI information and transmits the Frequency Domain Weights to a Wireless Access Point (WAP). In the transmitter and receiver of the WAP, the Frequency Domain Weights are applied to signals received and to be transmitted.

A holster for a telecommunication device includes a self-contained power source for driving an alert and a detector. The detector detects the presence and unseating of an telecommunication device that is insertable into the holster. The alert is coupled to the detector and is operable to alert to a user when the telecommunication device is removed from the holster. In this way the user is warned of the imminent loss or theft of the communication device.
摘要:
A method according to one embodiment identifying the frequency range of at least one active channel of at least one wireless communication RF band; identifying the frequency range of at least one clock harmonic; identifying an overlap, in whole or in part, between the frequency range of the at least one active channel and the frequency range of the at least one clock harmonic; and shifting a fundamental frequency of the at least one clock to shift the frequency range of the at least one clock harmonic out of, at least in part, the frequency range of the at least one active channel. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment.
