Analytical expressions are derived for the CraḿerRao (CR) lower bound on the variance of frequency estimates for the two-signal time-series data models consisting of either one real sinusoid or two complex sinusoids in white Gaussian noise. The expressions give the bound in terms of the signal-tonoise ratio (SNR), the numberN of data samples, and a function dependent on the frequency separation and the initial phase difference between the two signal components of each model. The bounds are… CONTINUE READING
