摘要： An audio transmission system including a wireless digital microphone unit which detects audio signals and wirelessly transmits the detected audio signals based on adjustable transmission settings and transmission parameters, and a central unit. The central unit has a monitor unit for monitoring and analyzing a frequency spectrum of an available frequency band, a link adaptation unit which adapts the microphone's transmission settings and parameters based on the results of the monitor unit, and a transmitting/receiving unit for receiving wirelessly transmitted audio signals from the wireless microphone unit and for transmitting transmission settings and transmission parameters via a return channel to the wireless microphone unit. The microphone's transmission settings and parameters are modified based on the transmission settings and transmission parameters transmitted via the return channel, which have a center frequency of a channel, a selection of a modulation method and parameters thereof, a data rate, and/or a channel encoding.

摘要： The present invention relates to a method for adjusting the amplification of a high frequency signal, a transmitter or receiver unit and a communication system. The aim of the invention is to provide a method and device for improved use of a polar-loop concept in a transmitter, especially for a mobile radio link. According to the method for adjusting the amplification of a high frequency signal, wherein the phase angle and the amplitude of an error-free input signal are separated from each other with a defined part of an output signal and readjusted, an output voltage of a battery voltage modulator is evaluated as a measure for an error at the output of a transmitter amplifier and taken into account in order to provide a correction.

摘要： According to the present invention, the resistance to interference of a transmitting device, which is particularly embodied as a high frequency transmitter with a transmitter amplifier may be improved, whereby a loss-affected network, for example, in the form of a matching resistance, is coupled to the output of the transmitter amplifier, particularly in the case of low output power of the transmitter amplifier, in order to introduce an impedance-matching at the output of the transmitter amplifier. As such, the reflection of an interference signal coming from a transmitter antenna at the output of the transmitter amplifier can thus be reduced.
