摘要
A system and method for detecting and selecting peaks in a delay power profile (DPP) signal. An adaptive threshold is used to determine valid paths in the DPP signal. The adaptive threshold is determined by measuring the signal-to-noise ratio of the DPP signal, and setting the threshold to minimize non-detections and false alarms in path estimation. To determine the signal-to-noise ratio, the system uses an iterative process wherein a raw estimate and an improved estimate are made of the noise.
