A PLM takes into account PLmax, the shadowing margin, the frequency, the height of the base station and the height of the mobile base station.
It is shown that by assuring constant phase margin on a frequency range around the roll-off frequencies the resulting control system is robust to parameter variations and nonlinear effects.
Thereby, the tuning parameters are the phase margin and crossover frequency.
The LTI controller design for the uncertain plants is carried out by minimising gain-phase margin and tracking frequency domain based performance objectives.
Comparisons with OTAs made with conventional SOI nMOSFETs, are performed showing that the GC OTAs presents larger open-loop voltage gain without degrading the phase margin, unit gain frequency and slew rate simultaneously with a significant required die area reduction depending on LLD/L ratio used.
There was no significant difference in patient age, excision margin status, or frequency of additional radiation or hormonal treatment between the subgroups with or without recurrence.
In line with design objectives, frequency-dependent optimization problems are formulated in LMI framework to maximize robust performance at low and high frequencies, and directly improve the robust stability margin at mid frequencies.

Therefore, exploiting the proposed methodology and recognizing the frequency margins of PU transmissions, SUs are able to select coherent secondary channels, hence, achieving increased expected availability and experiencing less reconfiguration costs.
Depending on the configuration and frequency margins, to calculate a MS matrix can take around 400 times more than to calculate MFCCs on the same signal frame.
