To achieve the maximal possible SE, we determined the minimal channel spacing applying that both system will work with sufficiently high Q-factor
, using flexible WDM frequency grid described in ITU-T G.
From both the BER and Q-Factor
analysis, it is clear that the proposed system provides better transmission capacity.
Figure 10 shows the variation of Q-factor
with current densities for three different QD-SOA lengths.
The measured Q-factor
of the coils is about 418, which is higher than values reported previously in [10,11].
calculated by the existing theoretical expression is usually much larger than actual value, because it is hard to include all kinds of losses into the expression .
And the quality factor (Q-factor
) of the LC tank is determined by the Q-factors
of the inductor and capacitor as in Equation (4).
The eye diagrams, BER and Q-factor
values of the signals are measured by the BER analyzers I and II at the base station and control station for downlink and uplink connections.
In particular, dissipation can be ascertained as the local changes in the Q-factor
of the cantilever (i.
The curves, based on the dielectric waveguide model, allow a designer to quickly predict the resonant frequency and Q-factor
of a rectangular DRA without the need to solve a transcendental equation.
On the other hand, the multivariate classification techniques, namely Q-factor
analysis and cluster analysis, categorize LD children based on patterns of test scores but do not employ a priori criterion (McKinney, 1984; Silver et al.
Optional physical-layer test software accommodates eye-diagram displays, eye-mask testing, jitter measurements, and Q-factor
display for testing USB, UWB, SONET, cable modems, and satellite and military systems.
is an addition to the company's Network Information Computers, and is designed to provide both dynamic protocol-independent and bit-rate-independent critical statistical measurements, including signal quality, optical eye profiling, network quality trending and network margin monitoring, in addition to traditional bit error rate testing.
