摘要： A biasing arrangement for an electronic apparatus having an input device is disclosed. The biasing arrangement comprises a bias voltage generator arranged to provide a bias voltage; a bias resistor connected between the bias voltage generator and the input device; and a reference voltage point of the input device, wherein a voltage of the reference voltage point of the input device is provided to the bias voltage generator for controlling the bias voltage in relation to the voltage of the reference voltage point of the input device. An electronic apparatus is also disclosed.

摘要： In a noise reduction circuit, a transistor circuit (21) receives power supply from a direct current voltage source (Vcc) through a power supply line circuit (24), and outputs an output signal by amplifying an input signal. An offset signal adding circuit (25) obtains and attenuates a part of the output signal, generates an offset signal, which has substantially the reverse phase and the same amplitude compared with those of a leak signal leaked to the power supply line circuit (24), and substantially offsets the leak signal by adding the offset signal to the leak signal.

摘要： The invention discloses a method (800) for use in a cellular wireless system (100) with a base station (120), a cell (110) in the system and a first user terminal (130) which can be scheduled for receiving traffic from the base station during a down link period, and for transmitting traffic to the base station during an up link period. There is a first guard period (TUD) between the up link period and the down link period, and a second guard period (TDU) between the down link period and the up link period. The method (800) comprises measuring the interference level in the cell for part of the time between two consecutive down link periods, and varying at least one of the following in accordance with the measured interference level: the duration of the first or second guard period, the duration of the up link period, or the traffic sent in the up link period.

摘要： The radio telecommunication terminal (2) comprises a data burst scheduler able to schedule the continuous transmission of consecutive data bursts which generate noise of similar energy on the radio-frequency channel as long as a specific radio-frequency channel is used to receive a radio signal, the respective energy of the noise generated by the transmission of two consecutive first and second data burst being similar only if the noise energy gradient between the end of the transmission of the first data burst and the beginning of the transmission of the second data burst is situated between predetermined upper and lower limits.

摘要： A method of operating a mobile device is disclosed. A first activity of the mobile device is detected. The following two operations are executed upon detection of the first activity; (i) wireless transmission of data over a wireless data link from a communication unit of the mobile device is disabled for a period of time, and (ii) a first control signal is transmitted from a communication unit to a satellite positioning system receiver of the mobile device, the first control signal enabling processing of signal positioning system signals received by the receiver during this period of time. The size of this period of time may be predetennined or adaptable.
