Abstract: A method is provided for offsetting a reference frequency of a quadrature reference clock signal. A quadrature reference clock (110) generates the quadrature reference clock signal at the reference frequency, while a quadrature variable offset clock (130) generates a quadrature clock signal at a base offset frequency based on a base offset value it receives from a control circuit (560). The base offset value can be determined in many ways, including reading it from a local memory (910) or receiving it from a remote device (1010). A polyphase mixer (140) performs a polyphase mixing operation between the quadrature reference clock signal and the offset clock signal to generate an agile clock signal having an agile clock frequency equal to the reference frequency plus the base offset frequency. If desired, the method can revise the offset frequency based on actual conditions and determine a corresponding revised offset value (920, 1020).

Abstract: A method is provided for receiving a data frame in an ultrawide bandwidth network. In this method, a device receives an ultrawide bandwidth signal containing a data frame. The device then performs an acquisition operation during a first preamble in the data frame, and identifies a marker after the first preamble that indicates that the first preamble has ended. After this, the device performs a signal processing operation during a second preamble in the data frame. After the training, the device then receives a header in the data frame, and then receives a payload in the data frame. By having a marker between the two preambles, this method provides a receiving device with critical information regarding the timing of the preamble section of a frame.

Abstract: A method is provided for training a rake finger (200). In this method the rake finger receives a data signal including a plurality of signal components having a plurality of signal phase values, respectively. (620). The rake finger then sets a current acquisition phase for a locally-generated signal (620) and then calculates a value of an autocorrelation function for the received data signal with the locally-generated signal at the current acquisition phase. (630). The rake finger determines when the autocorrelation function is at a peak value (640), saving the peak value in a storage device (290) when the autocorrelation function is at the peak value (650). The rake finger can then set a finger weight (W) for the rake finger based on the peak value stored in the storage device. This method can be performed at least in part during an acquisition process for the rake finger.
