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： 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： 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： A data transmitter (12) transmits parallel data as light pulses over multiple optical channels (14). A data receiver (16) converts the light pulses back to a voltage level and compares the voltage level to a reference capacitor voltage (42). The capacitor voltage should maintain a mid-range value for proper noise margin in detecting logic ones and logic zeroes. Any long series of consecutive logic ones or zeroes causes the capacitor voltage to charge or discharge toward the same level as the data voltage, which causes data errors. To prevent the data errors, the data is encoded (18) by inverting certain bits to break up the long series of consecutive logic states. The encoding information is transmitted as a transmitted clock to the data receiver over another fiber optic channel. The decoding information is retrieved (20) so that the encoded data can be converted back to proper logic states.

An optoelectric device (61) is coupled to the optoelectric board (20) using tape automated bonding tapes (47, 51). The optoelectric board (20) and the ferrule (11) are positioned adjacent each-other so that optical radiation is transmitted from the optoelectric device (61) to the optical fiber (17). The position of the optoelectric device (61) is adjusted to achieve an optimum position which is characterized by a maximum optical radiation transmitted to the optical fiber(17).
