Note When changing from 12 MHz to 6 MHz mode, the DSP on which the parameter is defined may no
longer be valid. If so, redefine the threshold on a DSP where the parameter is meaningful.

in (Interference + Noise) The interference plus noise power levels are computed by
the hardware on a burst-by-burst basis.
Note This parameter is available for a dual antenna system only.
inr (Interference + Noise Ratio) The ratio of the interference plus noise power levels
captured by the first antenna to the second antenna on a burst-by-burst basis. This
value is specified as a log to base 2 number.
constVariance (Constellation Variance) The average energy of the constellation error signal – the
error between the received (noisy) constellation symbol and the nearest ideal
constellation symbol. Constellation Variance is a measure of the Signal to
Interference plus Noise ratio (SINR) for that tone. On a single antenna system, it
represents (SINR)
-1
. On a dual antenna system, it represents a composite value
providing (SINR)
-1
after antenna combining.
timingOffset Represents the timing delay variations detected in the radio link.
