Correspondence: On Estimating the Angle Parameters of an Exponential Signal at High SNR
Date of Original Version
It is shown that at high signal-to-noise ratio, phase data alone is a sufficient statistic for the estimation of the angle parameters of a single exponential signal in Gaussian noise. The threshold effect, which occurs when estimating frequency based on phase only, can be deduced by examining the joint pdf of the phase and amplitude. © 1991 IEEE
