摘要： The application relates to transmission power control in transmission systems, in particular mobile radio systems. One object of the invention is to indicate a way of guaranteeing, compared with the state of the art, improved, in particular dynamic, control of transmission powers within predefinable emitted interference requirements with, in particular, increased efficiency and reduced power consumption. For this purpose, the invention provides for the filtering of an amplified transmission signal to be divided up between a narrower-band tunable pre-filter (4) and a broadband post-filter (10). To perform this operation, a signal-amplification circuit is proposed which comprises a tunable filter (4) which is connected downstream of a power amplifier (2).

摘要： The invention provides an apparatus for receiving electromagnetic signals with an improved capability to trace free or occupied channels. The invention comprises an assembly having a first frequency filter for filtering frequencies in a reception channel, when the apparatus is in the reception mode, or for testing one or more transmission channels, when the apparatus is in the tracing mode. The invention furthermore comprises a second frequency filter and a first switch for optional selection of the transmission or reception band. The change from the reception mode to the tracing mode is carried out, for example, by means of switches, and the bandwidth of the tuning of the oscillator, which provides a reference frequency by means of which the received signals are converted to an intermediate frequency, is reduced. This allows a particularly fast changeover.

摘要： In a telecommunications transmitter and receiver two IQ-mixers of the same type are operated in 180 degrees phase shift. In both the transmitter and receiver, an input signal is coupled to each IQ-mixer and the output signal of the mixers are combined so as to cancel unwanted error components in each individual output signal. In the transmitter, residual carrier signals are cancelled, and in the receiver, DC-offsets are cancelled. In both, the wanted signals are added, doubling the amplitude of the resultant output signal leading to four times more output power and improved dynamic range.

摘要： Transmission and reception device for a mobile radio base station comprising a plurality of transmission and reception units and hence a plurality of carriers, the transmission and reception units being accommodated in push-in modules and each having a modulator (10), a channel frequency device (19) and an output stage (20). At least some of the push-in modules comprise two full transmission and reception units having a first and a second transmission branch (1, 2). The two transmission branches (1, 2) are connected to a transmission connection (4) via an incorporated hybrid combiner (3) in order to provide two mutually combined carriers in a first mode of operation for relatively high capacity. In a second mode of operation for high output power, the two transmission branches (1, 2) are additionally connected to one another by means of an internal changeover device (25, 26, 27) such that the same transmitted signal is routed at least via the output stages (20) of both transmission branches (1, 2).

摘要： An apparatus and method for controlling the volume of a device's user alert sound based on an analysis of the device's environment. The device emits a signal and receives a resulting reflected signal. A processor measures characteristics such as the amplitude and/or delay of the reflected signal to determine the type of environment in which the communication device is located. The volume of the alert sound is then adjusted based on the type of environment indicated by the characteristics of the reflected signal. For example, if the characteristics indicate a closed environment, such as a briefcase, the volume is adjusted to high level, and if the characteristics indicate an open environment such as a desktop, the volume is adjusted to a low level.
