Abstract
The
k-PHD method, a generalization of the well-known Pisarenko harmonic
decomposition (PHD) method, is considered for frequency estimation of a single
real random-phased sinusoid in noise. With the use of a simple variance
analysis technique, an exact expression of the k-PHD frequency variance is
derived. An approximate k-PHD variance formula for sufficiently large data
lengths and signal-to-noise ratios is also given. Computer simulations are
included to validate the theoretical development.
