摘要： Methods, systems, and apparatuses are described for reducing the latency in a transceiver. A transceiver includes a high latency communication channel and a low latency communication channel that is configured to be a bypass channel for the high latency communication channel. The low latency communication channel may be utilized when implementing the transceiver is used in low latency applications. By bypassing the high latency communication channel, the high latency that is introduced therein (due to the many stages of de-serialization used to reduce the data rate for digital processing) can be avoided. An increase in data rate is realized when the low latency communication channel is used to pass data. A delay-locked loop (DLL) may be used to phase align the transmitter clock of the transceiver with the receiver clock of the transceiver to compensate for a limited tolerance of phase offset between these clocks.

摘要： A receiver simultaneously receives a plurality of signals on a plurality of channels, which have been modulated using frequency shift keying (FSK). A calculation range controller detects a Mark frequency and a Space frequency for each channel, determines for each channel a frequency range for Fourier transform calculation of the plurality of receiving signals, based on the detected Mark frequency and the detected Space frequency and indicates the frequency range to a frequency component detector. The frequency component detector performs Fourier transformation on the determined frequency range for each channel and detects, for each channel, frequency components (FFT signals) of the plurality of receiving signals respectively. The channel shifter allocates the FFT signals output from the frequency component detector to data of channel 1 to channel N and outputs the signals to respective demodulators.

摘要： A communication apparatus includes transmission circuitry and a frequency conversion unit. The transmission circuitry is configured to down-convert an input Intermediate Frequency (IF) signal using a transmit (TX) Local Oscillator (LO) signal so as to produce a TX baseband signal, to up-convert the TX baseband signal to produce an output Radio Frequency (RF) signal, and to send the output RF signal to an antenna. The frequency correction unit is configured to estimate a frequency of the TX baseband signal or of the input IF signal, and to adjust the TX LO signal based on the estimated frequency so as to cause the transmission circuitry to down-convert the input IF signal to a predefined target frequency.

摘要： Described are a method for generating a metric that is a function of a phase difference between a modulated carrier and a local carrier, and a phase detector for performing such a method. A baseband symbol is obtained from the modulated carrier, and the phase of the symbol is determined. Assuming that the modulation used to modulate the modulated carrier has a constellation diagram with M-fold rotational symmetry, the metric can be generated from the phase by evaluating a base function that includes a triangle wave having positively and negatively sloped linear segments whose slopes have identical absolute values and that is periodic with a period of 2π/M radians. Alternatively or additionally, if the ideal symbol phases are uniformly distributed, the metric can be generated by evaluating a version of the base function in which the ideal symbol phases correspond to identically valued metrics located on the triangle wave.

摘要： A method and apparatus for a receiver system in a receiver that includes at least two front end branches, each branch having its own intermediate frequency (IF) mixer to shift a received signal to an IF. When receiving multiple independent signals, the signals are digitized and the receiver performs a digital complex transform on each signal to obtain the corresponding quadrature component. When receiving a single signal the signal is routed to two mixers that are 90 degrees out of phase to obtain the quadrature signal components in the analog section of the receiver.

摘要： Provided are a power supply device, a power receiving device, a charging system, and an obstacle detection method that obtain a sufficient obstacle detection sensitivity even when an obstacle is small. A modulation unit (202) performs amplitude modulation or phase modulation on a test data sequence output from a test data sequence storage unit (201). A power control unit (203) generates, according to an instruction from a determination unit (204), a power control signal for increasing the power level of the test data sequence every time when the test data sequence is transmitted. The determination unit (204) determines whether there is an obstacle between the power receiving device and the power supply device based on whether the test data sequence output from the test data sequence storage unit (201) coincides with the test data sequence output from a power-transmitting-side receiving circuit (124).
