    • There is described a method for compensating the phase and gain distortions of a transmitter analog front end affected by a leakage of a local oscillator. The method comprises generating a single complex tone signal in a digital front end, wherein the generation comprises compensating the signal gain and phase with gain and phase offsets. The method comprises feeding the compensated signal into the transmitter analog front end. The method comprises feeding a corresponding output signal of the transmitter analog front end into a nonlinear component, thereby generating an inter-modulation between the complex tone signal and at least one tone signal due to the local oscillator leakage. The method comprises feeding the output of the nonlinear component into a measurement receiver analog front end. The method comprises filtering the output of the measurement receiver analog front end with a band pass filter in order to isolate the inter-modulation, which is indicative of the distortions introduced by the transmitter analog front end. The method comprises measuring the power of the filtered signal. The method comprises updating the gain and phase offsets according to the measured power, by reducing said measured power. The disclosure also relates, in particular, to a digital front end, to an analog system, to a telecommunication device, to a computer program, and to a storage medium.

    • A method is disclosed for paging of a terminal having a first subscriber identity (IMSI1) attachable to a first mobile communication network (101) and a second subscriber identity (IMSI2) attachable to a second mobile communication network (201). The method is performed in a controller node (213; 600) of the second mobile communication network and involves registering (310, 410) the terminal's second subscriber identity (IMSI2) as attached to the second mobile communication network (201), followed by registering (320, 420) an auxiliary paging address (422) for the terminal's second subscriber identity. Then, a need to page the terminal's second subscriber identity is determined (330), and the terminal's second subscriber identity is paged (340). The paging involves sending (240) an auxiliary paging message (442) to the registered auxiliary paging address, and the auxiliary paging message is adapted for delivery to the terminal's first subscriber identity (IMSI1).

    • Controlling the output power of a radio transmitter includes operating the transmitter at an initial power level setting and making an output power measurement. The measured value is adjusted by a desired incremental value and the adjusted value is then compared with the power of the original baseband signal to obtain a representation of what the gain should be if the radio transmitter power is properly adjusted to achieve the desired incremental value. The output power of the radio transmitter is than actually adjusted, and the actual gain is measured. The difference between the actual gain and the representation of what the gain should be if the radio transmitter power is properly adjusted is used to determine a further power adjustment of the radio transmitter that will reduce the difference.
    • 控制无线电发射机的输出功率包括在初始功率电平设置下操作发射机并进行输出功率测量。 测量值通过期望的增量值进行调整,然后将调整后的值与原始基带信号的功率进行比较,以获得如果无线电发射机功率被适当地调整以达到期望的增量值,增益应该如何的表示。 无线电发射机的输出功率不是实际调整的,实际的增益是测量的。 如果无线电发射机功率被适当调整,则实际增益与增益应该表示的差异用于确定将减小差异的无线电发射机的另外的功率调整。

    • A current mirror circuit exhibits improved current matching by applying a switching signal to ground path switches in series with transistors in both a reference path and an output path of the current mirror. The switching signal may comprise a high-frequency signal, which may be phase modulated. A plurality of matched, parallel-connected output transistors may be selectively enabled by qualifying the switching signal applied to each corresponding series-connected ground path switches by decoded digital modulation data. In one embodiment, the modulation data is decoded to thermometer-coded representation. In one embodiment, the switching signal path is identical to the reference and output circuits.

    • A method is disclosed of switching the active subscriber identity of a communication terminal which is capable at each moment in time of having only one active subscriber identity. An active subscriber identity switch from a first subscriber identity to a second subscriber identity is initiated. At least one parameter associated with a time of expiry of a timer associated with the first subscriber identity is stored. The first subscriber identity is deactivated and the second subscriber identity is activated. If an active subscriber identity switch from the second subscriber identity to the first subscriber identity is initiated and the first subscriber identity is activated, it may be determined whether the time of expiry of the timer associated with the first subscriber identity has passed. Network registration of the first subscriber identity may be performed only if the time of expiry of the timer associated with the first subscriber identity has passed. Corresponding computer program product, controller, arrangement and communication terminal are also disclosed.
