摘要： An NFC-B enabled listen device such as a smart mobile phone (1) is adapted by means of a controller implementing a control method to respond to a poll request signal (SENSB_REQ or ALLB_REQ) received from a read device (R). The read device may be another NFC-B enabled smart device such as another smart phone (R). In response to the poll request signal the listen device transmits a collision emulation signal. The collision emulation signal may be formed by adding and thereby simultaneously transmitting two or more poll response signals associated with two or more NFC-B applications running on the smart mobile phone (1). Alternatively the smart mobile phone (1) will send a synthesised pre-recorded collision emulation signal. Where the read device (R) is set to run the known NFC-B collision resolution process, the receipt of the collision emulation signal will provoke the read device (R) to increase the number of time slots available to receive poll response signal. According to the collision resolution process the increased number of slots is reported in a subsequent poll request signal. This enables a reliable, energy and time efficient resolution of all NFC-B applications active on the listen device without modification of the NFC-B read device.

摘要： A method in a radio receiver for detecting an AWGN channel, which radio receiver comprises a rake receiver. The radio receiver receives a propagation channel from a transmitter and determines that the received propagation channel is an AWGN channel when a filtered version of a minimum value of a metric is lower than a threshold value. The metric relates to a difference between a normalized measured power profile of the propagation channel and a normalized power template, which normalized power template is dependent on a number of sampling timing errors resulting when matching the power template to the measured power profile, and on a rake finger position within the rake receiver.

摘要： A data packet belonging to a received OFDM signal comprises a first training filed (STF) containing a number of preambles and a second training field (LTF) beginning by a guard interval (GI2).
The symbol boundary between the STF and the LTF is determined by: detecting (1) the beginning of the STF field, triggering (2) an Automatic Gain Control process and after locking of said automatic gain control process, determining (3) the autocorrelation peaks of the remaining STF preambles.
The symbol boundary is estimated (4) said from the times of said autocorrelation peaks.

摘要： A calibration method disclosed herein calibrates at least one of a capacitive load and a charging current controlling a charge-to-digital timer (CDT). In general, the disclosed calibration method measures multiple calibration phases based on start and stop signals separated by a known time difference, and therefore having a known phase, and adjusts at least one of the capacitive load and the charging current of the CDT based on the measured calibration phases. In so doing, the disclosed calibration method reduces power dissipation and peak supply currents over the frequency range of the CDT.

摘要： Sample-and-hold circuits typically operate at maximum speed when the sampling phase is much shorter than the holding phase. Thus, a device driving the sampling capacitor is disconnected most of the time. Methods and apparatus use the holding phase to store the full charge required by the sampling capacitor to track the amplifier output in at least two "boost" capacitors configured such that when the sampling capacitor is switched to the driver, the boost capacitors are also switched to the driver. Thus, the sampling capacitor is almost instantly charged to the required voltage, and the driver needs to supply only any remaining "error" charge, avoiding delays due to driver output slewing.
