Abstract: Apparatus and methods are provided for determining AR filter coefficient and numbers of synchronization. In one novel aspect, the AR filter coefficient and times of synchronization are determined based on the temperatures of the oscillator. In one embodiment, the UE determines a temperature drift rate by collecting sets of temperatures before and after the UE in the sleep mode of the CDRX, generates one or more threshold look-up tables and performs an optimization selection based on the temperature drift rate and the one or more threshold of look-up tables, wherein the optimization selection comprising selecting an alpha coefficient and a number of subframes for synchronization. In another embodiment, the optimization selection is further determined based on a subcarrier spacing, and a channel type of being a static channel type and a fading channel type. The UE further performs an on-the-fly oscillator S-curve calibration based on the set of temperatures.

Abstract: A test and measurement system includes a proximity coupling device to transmit a modulated carrier signal and a proximity integrated circuit card to load modulate the transmitted modulated carrier signal and generate a modulated subcarrier signal on the wireless carrier signal. A test and measurement instrument acquires the modulated carrier signal and includes a phase-aligned subcarrier demodulator to demodulate the carrier signal including the modulated subcarrier signal. A demodulator detects commands and responses in the modulated carrier signal, removes the commands, and identifies a correlation index for each response. Each correlation index indicates a phase of the modulated carrier signal of the corresponding response relative to a replica carrier signal. The demodulator adjusts the phase of the replica carrier signal based on the correlation index for each response and down converts each response using the phase-aligned replica carrier signal. The modulated subcarrier signal is low pass filtered to demodulate response.

Abstract: An optical sender is disclosed, which alone makes it possible to reliably decide whether modulation timing is correct or incorrect and to adjust the modulation timing. The optical sender includes: a first modulator that outputs a first optical pulse train subjected to intensity modulation; an asymmetric interferometer that outputs a second optical pulse train of double pulses; a second modulator (104) that outputs a third optical pulse train subjected to send-data modulation for each pulse pair; nd an optical intensity measuring device that measures an optical intensity of the third optical pulse train, a controller, when changing either of a first optical pulse train according to intensity modulation pattern and a second optical pulse train according to send-data modulation pattern, decides whether the modulation timing is correct or incorrect, based on optical intensity of the third optical pulse train.

Abstract: A method for determining a nonlinearity characteristic of a receiver path includes generating a set of N×M digital samples by repeating N times selecting an scaling factor from a set of N scaling factors, generating a version of a test signal, the version of the test signal corresponding to a test signal scaled by the respective scaling factor, processing the respective version of the test signal in at least a part of the receiver path to generate a respective processed signal, and storing M digital samples corresponding to the respective processed signal. Fourier-transformed data are generated using at least a portion of the set of N×M digital samples and a nonlinearity characteristic of the receiver path is determined based on the Fourier-transformed data.
