  • Publication number: 20140181348
    Abstract: Techniques for decoding encoded data are described herein. An example of a device in accordance with the present techniques includes a receiving signaling module coupled to a plurality of signal lines. The signaling module includes a receiver to receive a plurality of encoded line voltages or currents on the plurality of signal lines of a bus, wherein each one of the plurality of encoded line voltages corresponds to a weighted sum of data. The signaling module includes a comparator to determine the voltage level of each line at a unit interval and convert the voltage level to a digital value. The signaling module includes a lookup table correlating the digital value with a digital bit stream.

  • Patent number: 8611478
    Abstract: 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.

  • Patent number: 8385485
    Abstract: In some embodiments an adaptive clocking controller determines a clock spread of a system clock that would result in a lowest total interference between a channel received by a radio receiver and the system clock. A clock generator modifies a spread of the system clock in response to the determined clock spread. Other embodiments are described and claimed.

  • Publication number: 20080240266
    Abstract: In one embodiment of the present disclosure, a method for improving communication between a transmitter and a receiver is disclosed. The method can include receiving a first signal having a first power level over a first path, receiving a second signal having a second power level over a second path wherein the first path is different than the second path. The method can compare the first power level with the second power and determine a difference between the first power level and the second power level. The method can also adjusting a parameter in the system to reduce the difference in power levels between the first and second signals compensating for interference cause by many sources.
