Field Documentation

cfo_hz

int32_t ieee154_esp_sdr_measurement::cfo_hz

Carrier offset in Hz (meaningless without a signal), wraps at +-500 kHz.

coarse_cfo_hz

int32_t ieee154_esp_sdr_measurement::coarse_cfo_hz

Coarse carrier offset in Hz, unambiguous within +-1.5 MHz.

power_dbfs

int32_t ieee154_esp_sdr_measurement::power_dbfs

Mean power relative to the receive full scale.

samples_used

uint32_t ieee154_esp_sdr_measurement::samples_used

Samples above half the mean power that went into the estimate.

steps

uint32_t ieee154_esp_sdr_measurement::steps[8]

Histogram of the one-chip phase steps in 45 degree bins from -180 degrees: O-QPSK fills the bins at -90 and +90.
