Code multiplexing for asymmetric communication
Various embodiments provide for data transmission using modulated carrier signals to carry data, where the carrier signal comprises a predetermined sequence of symbols. An embodiment can be used in such applications as data network communications between sensors (e.g., cameras, motion, radar, etc.) and computing equipment within vehicles (e.g., smart and autonomous cars).
DEMODULATOR FOR AN ISOLATION COMMUNICATION CHANNEL FOR DUAL COMMUNICATION
An integrated circuit includes a demodulator to demodulate a signal simultaneously transmitted over an isolation communication channel and obtain gate information and configuration information. The demodulator includes a gate demodulation path and a configuration demodulation path. The received signal oscillates at a first frequency to represent a first state, oscillates at different frequencies to represent a seconds state, oscillates at a third frequency (or third and fourth frequencies), which are lower than the first frequency, to represent a third state, and the received signal is steady state to represent a fourth state. The gate demodulation path detects the first and second states. The configuration demodulation path includes first and second sub-demodulation paths. An envelope detector in the first sub-demodulation path detects the second state and the second sub-demodulation path detects the third state. The configuration demodulation paths uses an output of the gate demodulation path.

Systems and methods for use in authenticating users in connection with network transactions
Systems and methods are provided for authenticating a user in connection with a network transaction by the user, based on a biometric combination for the user. One exemplary method includes receiving an authorization request for a network transaction by a user where the authorization request includes biometric data representing at least first and second biometrics of the user. The method also includes converting the biometric data to a personal identification number (PIN) specific to the biometric data, where the first biometric is converted to a first character of the PIN and the second biometric is converted to a second character of the PIN. The method further includes appending the PIN to the authorization request and transmitting the authorization request to an issuer, thereby permitting the issuer to approve or decline the network transaction based, at least in part, on the PIN included in the authorization request.
Wireless receiver apparatus and method
Embodiments of the invention include a wakeup receiver (WRX) featuring a charge-domain analog front end (AFE) with parallel radio frequency (RF) rectifier, charge-transfer summation amplifier (CTSA), and successive approximation analog-to-digital converter (SAR ADC) stages. The WRX operates at very low power and exhibits above-average sensitivity, random pulsed interferer rejections, and yield over process.
Using multiple correlators to determine signal sent and frequency offset
A digital radio receiver is adapted to receive radio signals modulated using continuous phase modulation. The receiver includes components for receiving analogue radio signals having various carrier frequencies and a plurality of correlators corresponding to different bit sequences. Each of the plurality of correlators share a common estimator for estimating a frequency offset between the radio signals carrier frequencies and nominal carrier frequencies. The receiver further includes components allowing the estimator to determine which of the correlators produce the most optimal output signal.
Transmitter, receiver, and wireless communication method thereof
A transmitter is configured to transmit a radio frequency (RF) signal to a receiver. The receiver is configured to receive the RF signal and decode data. Furthermore, a method of wireless communication is provided between the transmitter and the receiver, in which the transmitter transmits to the receiver the RF signal. A carrier phase of the RF signal is randomly converted. The receiver detects an envelope of the RF signal, and extracts data from the RF signal.
