Detection of cisoids using least square error function
Abstract
In this paper, we propose a new hypothesis testing method for detection of cisoids (complex sinusoids) from a single measurement of data. The testing is performed on the least square error. The leastsquare error is shown to exhibit χ 2 distribution, which leads to an efficient threshold setup for the proposed method. The new method is a combined detection-estimation technique and provides improved performance over several existing techniques
