Sentence examples for variant constellations from inspiring English sources

For such a reason, we consider the optimization both over circularly symmetric and over rotationally variant constellations without any assumption about the circularity properties of the additive noise.

In practice, the PAM architecture achieves optimum performance on 50 of the channels where the linear equalizer performs unsatisfactorily and the WL processing gain, specific to rotationally variant constellations, compensates for the smaller minimum-distance of the PAM constellation.

Such assumption allows one to consider both the conventional circularly symmetric constellations, such as -PSK and square -QAM with, and the rotationally variant constellations, such as the well-known PAM and its rotated version (for which it exists such that is real-valued and, consequently, ), non-square QAM (with since a different power is allocated to the in-phase and quadrature components).

However, it is important to point out that a rhombic transformation of a circular constellation makes it rotationally variant and, for some values of (e.g., ), the procedure in [2] provides a rotationally variant constellation.

For the sake of clarity, let us note that the procedure proposed in [2] does not allow one to exploit the potential advantage of a rotationally variant constellation when the WL MMSE receiver is employed.

First, to ensure that potential estimation errors do not bias the optimization results of the basic scenario, we determined the optimal process variant profiles for different parameter constellations.

In addition, individuals with certain constellations of genetic variants in the network genes may be more likely to respond to lithium treatment and/or be more vulnerable to comorbid cocaine abuse.

The method is based on the exploitation of a rhombic transformation that operates on a circularly symmetric constellation making it rotationally variant.

On the other hand, when a WL MMSE equalizer is employed, a rhombic constellation, which is rotationally variant, is not equivalent to the conventional 4-QAM since the achieved MMSE is dependent on as shown in (8).

By modeling the residual disturbance at the output of the WL equalizer as a white Gaussian (possibly rotationally variant) process, we have singled out constellation-design methods which minimize an upper bound of the symbol error rate.

Such a constellation of variants could provide a respectable tool for individual disease prediction, and the variants discovered would (because of their relatively large effect size) be valuable resources for detailed molecular and physiological study.
