  • Publication number: 20140146927
    Abstract: A method and adaptive processor for estimating a reference signal, comprising receiving or determining a number of groups and respective group sizes, each group associated with a range of delay values of the reference signal, determining a multiplicity of coefficients, each coefficient associated with a specific delay of the reference signal, determining a multiplicity of weights, each weight associated with one of the groups, multiplying each sample of the reference signal having a delay by a corresponding coefficient to obtain a first product, and summing a multiplicity of first products associated with a group into a group sum signal sample, and multiplying each group sum by a weight associated with the group to obtain a second product, and summing all second products to obtain an estimated signal value.

  • Publication number: 20140126726
    Abstract: Methods and systems are provided for enhanced stereo audio recordings in electronic devices. Stereophonic recording performance in an electronic device, using a first microphone and a second microphone in the electronic device, may be assessed; and processing of signals generated by the first microphone and the second microphone may be configured based on the assessed stereophonic recording performance. The configuring may comprises adaptively modifying the processing to enhance stereophonic recording performance, to match or approximate an ideal performance. The assessing of the stereophonic recording in the electronic device may be based on a type of each of the first microphone and the second microphone, and/or based on a spacing therebetween. The processing may be adaptively modified to simulate directional reception of signals by the first microphone and the second microphone when the microphones are omnidirectional.

  • Patent number: 8705384
    Abstract: In general, this disclosure is directed to techniques for remotely controlling a transmitter-side rate adaptation algorithm. According to one aspect, a method includes detecting, with a receiver device, that a packet received from a transmitter is corrupted. The method further includes sending, with the receiver device, a positive acknowledgement for the packet to the transmitter in response to at least detecting that the packet is corrupted. According to another aspect, a method includes determining, with a receiver device, a targeted outcome for a rate adaptation algorithm performed by a transmitter. The method further includes using, with the receiver device, positive acknowledgements to remotely control the rate adaptation algorithm performed by the transmitter based on at least the targeted outcome.

  • Publication number: 20140085001
    Abstract: A novel and useful radio frequency (RF) front end module (FEM) circuit that provides high linearity and power efficiency and meets the requirements of modern wireless communication standards such as 802.11 WLAN, 3G and 4G cellular standards, Bluetooth, ZigBee, etc. The configuration of the FEM circuit permits the use of common, relatively low cost semiconductor fabrication techniques such as standard CMOS processes. The FEM circuit includes a power amplifier made up of one or more sub-amplifiers having high and low power circuits and whose outputs are combined to yield the total desired power gain. An integrated multi-tap transformer having primary and secondary windings arranged in a novel configuration provide efficient power combining and transfer to the antenna of the power generated by the individual sub-amplifiers.
