In this correspondence, we present a Newton-based alternating projection (AP) algorithm for estimating the parameters of exponential signals in noise, and compare its performance with that of modified forward-backward linear prediction/backward linear prediction (FBLPIBLP), total least squares (TLS), and iterative quadratic maximum likelihood (IQML) methods using computer simulations. In the case of undamped sinusoids, the AP algorithm yielded lower threshold SNR than the others, while in the case of damped sinusoids, its threshold SNR is same as that of TLS, but is 1 dB lower than that of MBLP and IQML.
