Base Station Performance Model

At present the testing of power amplifiers within
base station transmitters is limited to testing at component level as
opposed to testing at the system level. While the detection of
catastrophic failure is possible, that of performance degradation is
not. This paper proposes a base station model with respect to
transmitter output power with the aim of introducing system level
monitoring of the power amplifier behaviour within the base
station. Our model reflects the expected output levels of second or
third generation CDMA base stations conforming to the Open Base
Station Architecture Initiative (OBSAI) open base station reference
architecture. The simulated base station output power is verified by
comparison to field data using such metrics as power
complementary cumulative distribution function (CCDF),
volatility, absolute deviation, mean absolute deviation and rate of
change.
