In [7], the author described a relay-assisted PLC system based on single-frequency networking condition.
DDBSE (DD based on single-frequency entropy) mainly modifies the weighting factor of DD in order to improve the accuracy of a priori SNR estimation.
In this paper, a novel modified decision-directed (DD) a priori SNR estimation approach based on single-frequency entropy, named DDBSE, is proposed.
Therefore, in this paper, a new DD approach based on single-frequency entropy named DDBSE is proposed, which combines DD and the approach in [1, 5, 11].
A network of global positioning system based on single (L1) frequency receivers has been installed in Brazil for the purpose of monitoring ionospheric L-band scintillation.
The theoretical minimum mean square error (MMSE) equalization weight for ANC based on single carrier with frequency domain equalization (SC-FDE) radio access is derived by taking into account the self-interference.
Sequencing of Fusarium graminearum, causal agent of Fusarium head blight of wheat and barley, coupled with expression profiling experiments revealed a set of 408 genes expressed exclusively during infection of barley that, based on single nucleotide polymorphism frequency were more divergent than other genes in the genome (17).
For example, Wang and Zhang suggested that 172 annotated genes were very unlikely to encode proteins in the genome of Vibrio cholerae based on single-nucleotide frequencies.
A whole-genome view of aberration frequencies (based on single sample PCF) and highly correlated aberrations (based on multi-sample PCF) are shown in Figure 6.
A more recent report based on single nucleotide polymorphisms estimated, however, the frequency of predicted bi-allelic mutations of CYP24A1 in the general population to be as high as 4 20% [ 9].
