  maximum signal
We are conducting experiments to determine the maximum signal-to-noise improvement that can be obtained in drill holes.
      
First, the downlink beamforming weights for the base-station antenna-array are designed based on the maximum Signal-Interference-Ratio (SIR) criterion.
      
It is shown that the maximum signal/noise ratio when the threshold sensitivity is limited by circuit noise corresponds to minimum surface conductivity.
      
In a number of critical problems of detection and estimation of the number of signals it is necessary to know the statistical properties of the maximum signal in order to choose correctly the threshold value and adopt statistical decisions.
      
Numerical comparison between average error rates shows that the maximum signal to noise ratio optimum filter is the better one, and leads to a receiver design with lower average error rate.

Objective To evaluate the role of dynamic contrast-enhanced magnetic resonance imaging (MRI) in the diagnose of prostatic cancer and benign prostatic hyperplasia (BPH), and to determine the correlation between dynamic MRI findings with angiogenesis.Methods Thirty-two cases of prostatic cancer and 40 cases of BPH underwent dynamic contrast-enhanced MRI.All the patients in this study were diagnosed by histopathology.The results of dynamic contrast-enhanced MRI were evaluated by early-phase enhancement parameters and time-signal intensity curves (SI-T curves), and the curves were classified according to their shapes as type Ⅰ, which had steady enhancement; type Ⅱ, plateau of signal intensity; and type Ⅲ, washout of signal intensity.The pathologic specimens of region of interest (ROI) were obtained, and HE staining, immunohistochemical vascular endothelial growth factor (VEGF), and microvessel density (MVD) measurements were performed.The relationships among dynamic contrast-enhanced MRI features, VEGF, and MVD expression were analyzed.Results In the early-phase enhancement parameters of dynamic contrast-enhanced MRI, onset time,maximum signal intensity, and early-phase enhancement rate differed between prostatic cancer and BPH(P<0.01, 0.05, 0.01), but there were some overlaps between them.The intermediate and late post-contrast periods were characterized with the lesion SI-T curves.The SI-T curve of prostatic cancer was mainly type Ⅲ (21 cases).Type Ⅱ could be seen in both prostatic cancer (8 cases) and BPH (19 cases).Type Ⅰ most appeared in BPH (18 cases).The distributions proved to have significant difference (P<0.001).The mean VEGF and MVD level of 32 prostatic cancer patients were significantly higher than those of 40 BPH patients (P<0.001).MVD level of prostatic cancer and BPH showed an association with VEGF level (P<0.01).The maximum signal intensity and early-phase enhancement rate in both prostatic cancer and BPH showed an association with MVD expression (P<0.05 or 0.01).Conclusion Dynamic contrast-enhanced MRI are useful in the diagnose and differential diagnose of prostatic cancer and BPH.The characters of dynamic contrast-enhanced MRI are closely related to VEGF and MVD level.As a noninvasive method, dynamic contrast-enhanced MRI has a potential role in evaluating the degree of angiogenesis of prostatic cancer and BPH.
