Order Statistics Approach for Detecting a Transient Signal of Unknown Arrival Time in Noise
نویسندگان
چکیده
Detecting a transient signal of unknown arrival time in noise is actually a binary hypothesis test problem, where the null hypothesis (noise only) is a simple one, while the alternative hypothesis is composite. The generalized likelihood ratio test (GLRT) is a common tool to solve such problems. In this paper we show how order statistics (OS) approach can be used to solve the same problem. We show that the two hypothesis becomes simple using the OS approach so a likelihood ratio test (LRT) can be applied, and we discuss the trade-offs between the two solutions. In particular, we point out cases where the OS detector outperforms the GLRT.

The Transient Behavior of LC and Ring Oscillators under External Frequency Injection
In this work, time domain analysis is used to solve Adler’s equation in order to obtain the required time, for an oscillator under external injection, reaching the steady-state condition. Mathematical approach has been applied to fully describe the transient of frequency acquisition in injection-locked LC and Ring oscillators considering their time-varying nature. Then, the analysis is verifie...
متن کاملSecrecy of Communications in Data Transmission by Impulses with Unknown Moments of Appearance and Disappearance
We carried out a comparative analysis of the algorithms for detecting a rectangular impulse against Gaussian white noise under either authorized or unauthorized access to the transmitted data. We presupposed that for data transmission the binary communication system is used and that the useful information in the data is whether the signal is present or absent. The case is that unauthorized acce...

متن کاملDetection and parameter estimation of a transient signal using order statistics
Detection and parameter estimation of a transient signal in noise is a problem of many applications. It is characterized by the fact that some of the measurements consist of noise only. Modern statistical signal processing techniques are applied on a discrete version of the received data and are implemented by digital signal processing (DSP). In this correspondence, we show how order statistics...
متن کاملDigital Binary Phase-shift Keyed Signal Detector
We have developed the effective algorithm for detecting digital binary phase-shift keyed signals. This algorithm requires a small number of arithmetic operations over the signal period. It can be relatively easy implemented based on the modern programmable logic devices. It also provides high interference immunity by identifying signal presence when signal-to-noise ratio is much less that its w...
