摘要： A core wireless engine design includes the standardized CWE interface. The core wireless engine includes a transceiver, microprocessor and a standardized interface arrangement. The standardized interface arrangement is adapted to be connected to a variety of different host interfaces. This arrangement allows core wireless engines to be used with a variety of different host interfaces and form factors. In a preferred embodiment, the core wireless engine design is sized so that it can fit into a variety of form factor units.

摘要： A receiver with reduced near field noise is described. The receiver has a far range receiving section configured to sense a desired signal that includes near field noise. The receiver further includes a near range receiving section configured to sense a near field noise reference signal. An adaptive noise canceller (ANC) of the receiver is configured to detect the magnitude of an error vector from the far range receiving section. The ANC is configured to adjust the phase and gain of the near field noise reference signal in response to the magnitude of the error. Accordingly, the ANC can generate a corrected near field noise reference signal that is added to the desired signal with an adder. The near field noise is canceled by the addition of the corrected near field noise signal. The ANC uses a least mean square technique to determine the amount of correction needed.
