    • The present invention is directed to a receiver for a wire-free communication system for reception of a received signal which is modulated using a digital modulation method having a first frequency conversion device for production of a frequency-converted received signal by conversion of the received signal to an intermediate frequency. The receiver further includes a pre-filter for production of a filtered received signal from the frequency-converted received signal such that the received signal is band-limited, and an analogue/digital converter for production of a binary received signal from the filtered received signal by comparison of the filtered received signal with a level threshold. In addition, the receiver includes a phase reconstruction device for production of a phase-reconstructed received signal by reproduction of the phase of the received signal from the time intervals between zero crossings of the binary received signal, and a mapping device for production of a bit sequence by mapping symbols from the phase-reconstructed received signal onto this bit sequence using the digital modulation method.
    • 本发明涉及一种用于无线通信系统的接收机,用于接收使用具有第一频率转换装置的数字调制方法调制的接收信号,该第一频率转换装置用于通过接收信号的转换来产生频率转换的接收信号 到中频。 接收机还包括一个预滤波器,用于产生来自经频率转换的接收信号的滤波后的接收信号,使得接收的信号受到频带限制;以及模拟/数字转换器,用于从滤波的接收信号产生二进制接收信号 通过比较滤波的接收信号与电平阈值。 此外,接收机包括相位重构装置,用于通过从二进制接收信号的过零点之间的时间间隔再现接收信号的相位和用于产生位的映射装置来产生相位重构的接收信号 使用数字调制方法将来自相位重构的接收信号的符号映射到该比特序列上。
