Table 84 briefly summarizes all the DPD/CLGC post initial calibration parameters described in the data structure.

Table 84. DPD/CLGC Post Initial Calibration Parameters

Parameter Type Description Min Max Default Note

numberOfSamples uint32_t Specifies the number of

samples to use for each

iteration of DPD

computation.

1024 4096 4096 The maximum

value is preferred.

additionalPowerScale uint32_t Provides an estimate of the

standard deviation of the

modem input data

magnitude to scale the data

for internal DPD

computation.

0 2

32-1

rxTxNormalizationLowerThreshold uint32_t

(U2.30)

Signal power for the lower

threshold for the

normalization of the

magnitude and phase of the

RX and TX data

0 1.0 0.0031622776602

(−25 dBFS)

rxTxNormalizationUpperThreshold uint32_t

(U2.30)

Signal power for the upper

threshold for the

normalization of the

magnitude and phase of the

RX and TX data

0 1.0 0.031622776602 (-

15 dBFS)

detectionPowerThreshold uint32_t

(U1.31)

Power threshold used for

invalid capture detection

detectionPeakThreshold uint32_t

(U1.31)

Peak threshold used for

invalid capture detection

countsLessThanPowerThreshold If the number of samples

below the

detectionPowerThreshold

exceeds this number, the

capture is discarded.

To disable the

detection, set it

to 4096

countsGreaterThanPeakThreshold If the number of samples

above the

detectionPeakThreshold is

less than this number, the

capture is discarded.

To disable the

detection, set it

to 0

immediateLutSwitching bool Determines whether the

LUT switches immediately

or at the end of Tx data

frame.

TRUE FALSE not

currently

supported.

useSpecialFrame bool DPD only runs on a user

indicated special frame.

FALSE Currently not

supported.

resetLuts bool Reset LUTs so that no pre-

distortion is applied.

FALSE User should reset

LUTs at the start

of DPD

operation.

timeFilterCoefficient uint32_t Coefficient of a time filter to

remove spectral spikes from

LUT swiching.

0 1.0 0 It helps if there

are spectral

spikes from LUT
