摘要: A transient detection method based on permutation entropy (PE) and generalized likelihood ratio test (GLRT) detector is proposed. PE can measure the complexity of time series, values noise signals are different. GLRT utilized to locate starting point in trajectory captured signal. This avoids difficulty threshold selection suitable both ramp step change signals. The from a mobile phone performance proposed method. Experimental results demonstrate that effective even low signal (SNR).
