摘要： The aim of the invention is to control the bass reproduction of audio signals in electroacoustic transducers based on the psychoacoustic principle denoted by the term “virtual pitch” or “residual hearing (hearing of missing fundamental)”, in such a way that the perception of the virtual bass reproduction of the audio signals is improved in relation to prior art. To this end, the reproduction of the low pitched frequencies or basses released in the electroacoustic transducer is controlled by the amplification of the harmonic waves already contained in the audio signals, in the form of a simulation, in such a way that the listener experiences or perceives an improved bass reproduction. The control or simulation can thus be carried out in both a digital manner, by means of a program module in a digital signal processor of an electronic appliance for outputting and/or reproducing audio signals using the electroacoustic transducer, and in an analog manner, by means of a hardware circuit between a digital analog transducer and a final amplifier of the electronic appliance for outputting and/or reproducing audio signals using the electroacoustic transducer.
摘要翻译：本发明的目的是基于由虚拟音调或“剩余听觉（缺少基本听觉）”表示的心理声学原理来控制电声换能器中的音频信号的低音再现，使得感知与现有技术相比，音频信号的虚拟低音再现得到改善。为此，在电声换能器中释放的低音调频率或低音的再现通过以模拟形式已经包含在音频信号中的谐波的放大来控制，使得听者经历或感觉到改进的低音再现。因此，控制或仿真可以通过电子设备的数字信号处理器中的程序模块以数字方式进行，用于使用电声换能器输出和/或再现音频信号，并且以模拟方式通过在数字模拟换能器和电子设备的最终放大器之间的硬件电路的装置，用于使用电声换能器输出和/或再现音频信号。

摘要： System and method for the registration of a mobile part (MT, OA, HA) in a base station (BS) in a telecommunication system designed for wireless communication between a mobile part (MT, OA, HA) and a base station (BS. The base station and the mobile part are initially placed in an access standby state. Subsequently, a verification procedure determines a message exchange (MA) between the mobile part and the base station if the base station supports a voice-controlled registration and if the mobile part is theoretically connected to the base station. If the theoretical connection is determined, a user channel connection suitable for the transmission of voice data is established between the mobile part and the base station. The mobile part is then either registered in the base station, or the registration attempt is rejected.

摘要： The disclosure relates to a communication terminal having a bandwidth expansion device for expanding the bandwidth of a narrowband voice signal, on a low-frequency and/or high-frequency side, by synthesizing at least one frequency band on the basis of the narrowband voice signal. A qualitatively satisfactory bandwidth expansion is thus performed using a plurality of net bit rates. The bandwidth expansion device is further connected to a memory containing a lookup table comprising at least one parameter value for the bandwidth expansion, for at least two net bit rates of the narrowband voice signal. A method for expanding a bandwidth of a narrowband voice signal having at least two net bit rates in a communication terminal is also disclosed herein.
