Abstract: Handling a frequency error (FEQ) of a terminal which includes a plurality of modems using a same clock source includes: obtaining the FEQ, which is a difference between a carrier frequency of a received signal and a nominal frequency for each modem; obtaining a FEQ threshold of the received signal in a current service based on the FEQ; obtaining an adjusted value of the clock source corresponding to each modem based on the FEQ and the FEQ threshold; obtaining a synthesized adjusted value of the clock source based on the adjusted values of all the moderns; and adjusting the frequency of the clock source based on the synthesized adjusted value of the clock source. The FEQ of the mobile communication terminal can be quickly corrected by adjusting the clock source's frequency, and, by considering the FEQ of all the modems, the modems' performances may be balanced.

Abstract: A receiver 10 and method in the receiver for cell search to find an actual base station having a carrier frequency in a radio communications network 1. The receiver detects a first signal representative of a base station 12, 14, 16, 18 by performing slot synchronisation, frame synchronization, cell identification, measurement of a signal quality of the first signal and comparison of the measured signal quality with a first threshold value. When a first signal having a signal quality that is greater than the first threshold value has been detected, the receiver searches for at least one second signal representative of a base station for at least one frequency offset comprised in a set of offsets S3. Further, when one or more second signals are detected, the receiver selects the signal with the highest signal quality, and detects a broadcast radio channel representative of a base station for the selected signal.

Abstract: A power consumption measurement method for operating an electronic component during an interval of time includes: logging power states that the component adopts during the interval, interrogating the log to determine the amount of time that the component spent in each power state during interval, and multiplying the rated power consumption for each state by the amount of time spent in each respective state. The power consumptions for each of the states are summed to determine a total power consumption of the component during the interval. Logging the power states may be achieved by counting command line instructions of different types, thus identify the beginning and end of each power state, during the interval. The method may be used to measure and/or benchmark the actual power consumption of a DDR RAM module. An apparatus for carrying out the method is also disclosed.

Abstract: There is described Audio driver circuit comprising a main, 1-bit digital-to-analog converter, adapted to receive a 1-bit oversampled digital audio signal. Thanks to an auxiliary digital-to-analog converter which converts into the analog domain a digital offset compensation value stored in e.g. an OTP memory register 34, and to a summing and filtering arrangement, it is possible to reduce the offset cancellation granularity in order to compensate for the offset of the main digital-to-analog converter in the output signal.

Abstract: An interference cancellation technique is implemented in a receiver adapted for determining an estimation of interferences when receiving an OFDM signal made of packets. Each packet includes a first training field, a second training field, a first header field, a second header field and a data field. The receiver detects a first symbol value of the first header field, and a second symbol value of the second header field, the first and the second header fields having been modulated using different modulation schemes. The estimation of interferences is determined using the first and the second symbol values.
