摘要： A wireless communication device comprises a first sub-system arranged to pass data to a second sub-system comprising timing synchronization logic operably coupled to a counter, such that data is sampled by the timing synchronization logic when passed to the second sub-system from the first sub-system wherein the wireless communication device is characterized in that the timing synchronization logic is arranged to determine a position of a first data frame and in response thereto initiate a counting process of the counter and determine a position of a second data frame and in response thereto determine a count value from the counting process of the counter and in response to the count value determine whether to initiate a timing advance or timing retard operation on the data being passed to the second sub-system. In this manner, the inventive concept provides the wireless communication device with a mechanism to achieve timing synchronization. In particular, the inventive concept may allow a radio frequency integrated circuit to implement timing synchronization by advancing or retarding an ‘actual’ signal sent from digital baseband circuits in a 3G DigRF wireless communication device.

摘要： A wireless receiver includes a hardware (HW) block, a converter block and a digital signal processor (DSP). The HW block receives a wireless signal having a first DC Offset Component (DCOC), removes a portion of the first DCOC to produce a residual DCOC centered at DC, and generates parameters that estimate the residual DCOC. The converter block is coupled to the HW block and receives the residual DCOC centered at DC and converts it to a residual DCOC centered at IF. The DSP is coupled to the HW block and the converter block and receives the residual DCOC centered at IF from the converter block and the parameters from the HW block, and uses the parameters to eliminate the residual DCOC, and generate a baseband signal that is substantially free of the first DCOC and the residual DCOC.

摘要： Apparatus, systems, and methods are provided for transmitting messages over a serial interface. A method comprises receiving a first signal at a first time and receiving a second signal at a second time, the second time being after the first time. If a difference between the second time and the first time is less than a threshold time period, the method comprises generating a first message that is representative of the first signal and the second signal and transmitting the first message over the serial interface. In accordance with one embodiment, the threshold time period is equal to one half of an interface acquisition delay time period associated with the serial interface.

摘要： Systems and methods are provided for controlling headroom of an amplifier (e.g., in a transmitter). A method comprises obtaining a target output power for a current interval and obtaining a target headroom for a subsequent interval. The method continues by adjusting, during the current interval, the power output capability of the amplifier based on the target headroom and adjusting the input power of an input signal based on the target output power, such that the output power of the amplifier is substantially constant during the current interval as the power output capability of the amplifier is adjusted.
