Appl. No.:

12/765097

Inventors:

Gaurav Chandra - Santa Clara CA, US
Moshe Malkin - Mountain View CA, US
Dariush Dabiri - San Jose CA, US

Assignee:

PLX Technology, Inc. - Sunnyvale CA

International Classification:

H04B 3/20

US Classification:

370286

Abstract:

Embodiments of a method and apparatus of reducing transmit signal components of a receive signal of a transceiver are disclosed. One method includes generating a transmit signal by passing a pre-driver transmit signal through a transmit driver. An echo cancellation signal is generated by passing the pre-driver transmit signal through an echo cancellation driver. A residual echo signal is generated by passing a pre-driver residual echo cancellation signal through a residual echo cancellation driver. The transceiver simultaneously transmits the transmit signal, and receiving the receive signal. At least a portion of an echo signal of the receive signal is canceled by summing the echo cancellation signal with the receive signal. At least another portion of the cancellation echo signal of the receive signal is canceled by summing the residual echo cancellation signal with the receive signal.

Assignee:

Teranetics, Inc. - San Jose CA

International Classification:

H04B 1/40

US Classification:

375219

Abstract:

Embodiments of methods and apparatuses for reducing electromagnetic interference in a receive signal are disclosed. One method includes receiving a receive signal. An analog cancellation signal is generated. The analog cancellation signal is summed with a receive signal, thereby mitigating electromagnetic interference in the receive signal. One apparatus includes a transceiver that includes a receive analog to digital converter (ADC) sampling a receive signal. Electromagnetic interference (EMI) processing circuitry generates an analog cancellation signal. The analog cancellation signal is summed with a receive signal, thereby mitigating electromagnetic interference in the receive signal.

PLX TECHNOLOGY, INC. - Sunnyvale CA

International Classification:

H04L 5/16

US Classification:

375220

Abstract:

Embodiments of methods, apparatuses, and systems for preprocessing a transmit signal of a transceiver are disclosed. One method includes estimating parameters of a communication link between the transceiver and a link partner transceiver, estimating cross-talk coupling of the transceiver to at least one other transceiver, and adjusting at least one of a transmit power or a transmit signal waveform based on the estimated parameters and estimated cross-talk. One apparatus includes a transceiver that is operative to obtain parameters of a communication link between the transceiver and a link partner transceiver, and to obtain a representation of cross-talk coupling of the transceiver to at least one other transceiver. Further, a controller of the transceiver is operative to adjust at least one of a transmit power level or a transmit signal waveform based on the estimated parameters and estimated cross-talk.

Abstract:

Embodiments of methods, apparatuses, and systems for signal processing of multiple input signals to control peak amplitudes of a combined signal are disclosed. One method includes receiving a plurality of input signals, generating a combined signal, the combined signal comprising a plurality of sub-channels, wherein each sub-channel includes a representation of at least a portion of at least one of the plurality of input signals, and processing the representation of the least a portion of the at least one of the plurality of input signals of at least one of the sub-channels, to reduce a peak-to-average-power ratio (PAR) of the combined signal.

International Classification:

G06F 3/041
G06F 3/044

Abstract:

Errors in touch signals due to grip and finger coupling to routing traces can be compensated. In some examples, reference traces can be provided to measure a signal contribution from a user's grip to routing traces. In some examples, shielding electrodes can be provided to reduce fringing field coupling between a user's grip and routing traces that are missing a neighboring trace. In some examples, a global correction for finger to trace coupling can be performed based on stored matrices that characterize cross-coupling between touch sensor electrodes in a touch sensor electrode array. In some examples, a determined touch location can be used to apply localized matrix correction to a subset of touch sensor electrodes in the touch sensor electrode array. In some examples, correction for multiple touch locations can be corrected in a specified order to avoid compensating for crosstalk effects of a single touch sensor electrode multiple times.

H04B 5/00

Abstract:

A wireless power transmitting device transmits wireless power signals to a wireless power receiving device using a wireless power transmitting coil. The wireless power receiving device may transmit data packets to the wireless power transmitting device. The wireless power transmitting device may include a data receiver that is coupled to the wireless power transmitting coil and that receives the transmitted data packets. The data receiver may be configured to demodulate the received data packets. The data packets may include at least preamble bits, start bits, and data bits encoded as biphase half-bit signals in accordance with a predefined wireless power transfer protocol. During demodulation, the receiver may perform preamble detection, start bit detection, and data bit detection by comparing the input signals to corresponding reference patterns using a maximum likelihood sequence detection scheme. Phase recovery may be employed throughout to help provide immunity to phase change.
