This paper considers the problem of estimating
the spectrum of real-valued signals. We propose
real-valued versions of the Capon and the APES spectrum
estimators. The estimators are derived as members of the
Matched-Filterbank (MAFI) estimator class introduced in
[Stoica et. al., Signal Processing, 66(1)].
Furthermore, we show that the real-valued estimators
will be unbiased, whereas the complex-valued estimators
will have a (slight) bias for real-valued data.
Finally, we conclude the paper with a numerical example
illustrating the performance of the proposed estimator.
