用于识别相邻信道被信号占用的方法和装置
摘要：
本发明涉及借助一个具有有用信道部分和/或相邻信道部分的复数值带通信号来识别相邻信道被信号占用的方法。根据本发明，a)推导一个实数值的带通信号，其方式是该复数值的带通信号被滤波并且由该被滤波的信号形成实部，b)将该实数值的带通信号转变为一个第一基带信号，c)对该第一基带信号进行滤波，使得被有用信道部分影响的频谱部分被抑制，以及d)分析该第一被滤波的信号并且根据被该分析的第一被滤波的信号产生一个二进制的占用信号，用于说明相邻信道的占用。本发明此外还涉及相应的用于占用识别的装置，以及具有这种装置的发送/接收装置和集成电路。
摘要（英）：

A method for detecting occupation of an adjacent channel by a signal with the aid of a complex-valued bandpass signal having an information channel component and/or an adjacent channel component. In accordance with the invention, a) a real-valued bandpass signal is derived in that the complex-valued bandpass signal is filtered and the real component is produced from the filtered signal, b) the real-valued bandpass signal is transposed into a first baseband signal, c) the first baseband signal is filtered so that spectral components influenced by the information channel component are suppressed, and d) the first filtered signal is evaluated and a binary occupation signal is generated to indicate the occupation of the adjacent channel as a function of the evaluated first filtered signal. The invention further discloses a corresponding device for detecting occupation, as well as a transmitting/receiving device and an integrated circuit having such a device.
