| Abstract:
|
This paper presents a methodology towards the emulation
of the electrical power consumption of the RF device during
the cellular phone/handset transmission mode using the LTE technology.
The emulation methodology takes the physical environmental
variables and the logical interface between the baseband and the
RF system as inputs to compute the emulated power dissipation
of the RF device. The emulated power, in between the measured
points corresponding to the discrete values of the logical interface
parameters is computed as a polynomial interpolation using polynomial
basis functions. The evaluation of polynomial and spline curve
fitting models showed a respective divergence (test error) of 8%
and 0.02% from the physically measured power consumption. The
precisions of the instruments used for the physical measurements have
been modeled as intervals. We have been able to model the power
consumption of the RF device operating at 5MHz using homotopy
between 2 continuous power consumptions of the RF device operating
at the bandwidths 3MHz and 10MHz. |
