If k = 0, it denotes the signal term.
resolution bandwidth (electronic signal term used in spectrum analyzers and EMI/EMC testing).
For Figure1b, the maximum peak results from signal term while other peaks are from cross terms.
Notice, we account for the angular uncertainty only in the interference terms, but not in the signal term.
As expected from (17) and (18), since the correlation between the input and output signals becomes higher as we increase IBO, the effective signal term (C0) increases, whereas the other terms that represent residual distortions decrease.
The magnitude of the IQ image component, represented by the conjugated signal term in (1), can be characterized with the image rejection ratio (IRR) as 10 log10(|K 1, j |2/|K 2, j |2).
Therefore, the information signal term S k follows the distribution of S = t(X +(1 - δ Y) which is described as the sum of two Gamma variables X and Y.
Down the receiver chain, the noisy signals and are mixed together, and the mixed signal contains the desired signal term (first term below) and three interference cross-terms given by (10).
From the above, the moduli of signal term and cross term are sin Mπ f p / f s sin π f p / f s and sin M − k π f p / f s sin π f p / f s, respectively.
Accordingly, the signal term is get as exp j 2 π f 0 f s + jπu 2 n + 1 f s 2 ∑ m = 1 M exp j 2 π m − 1 f p f s (8).
In Lemma 2, we define both the interference term and the information signal term such as I k = | | h ̄ k, a eff | | 2 sin 2 θ k, a and S k = | | h ̄ k, a eff | | 2 cos 2 θ k, a.
