摘要： A method is provided for demodulation of an analog receive signal (y'(t)) carrying information, wherein a number (M) of more than two analog signals (y
m (t)) is formed from the receive signal (y'(t)) in separate channels (8), such that the receive signal (y'(t)) is multiplied in each case by a period function, the phase ((φ
m ) thereof respectively differing in the channels (8), and wherein the multiple signals (y
m (t) are each low-pass filtered, and a corresponding demodulator (1).摘要翻译： 提供一种用于对携带信息进行模拟接收信号的解调的方法，其中在单独信道中从接收信号形成多于两个的模拟信号的数目，使得接收信号在每种情况下与周期函数相乘，其相位 分别在通道中不同，并且其中多个信号各自被低通滤波。

摘要： The present invention relates to a method of determining a distance or location of a remote device or reflector, the method comprising: receiving a signal from a remote signal transmitter associated with or contained in or attached to the remote device; estimating a first propagation delay associated with the received signal, wherein the first propagation delay represents a first candidate for a correct propagation delay; deriving a relationship between the first candidate and one or more other candidates for a correct propagation delay from the received signal; determining a plurality of other candidates for a correct propagation delay based on said relationship; generating a likelihood histogram based on said candidates for a correct propagation delay; selecting a propagation delay from said candidates based on the likelihood histogram; and determining a distance or location of the remote device or reflector using the selected propagation delay.
