Detailed Description

Enumeration Type Documentation

snr_est_type_t

enum gr::digital::snr_est_type_t

A block for computing SNR of a signal.

Below are some ROUGH estimates of what values of SNR each of these types of estimators is good for. In general, these offer a trade-off between accuracy and performance.

• SNR_EST_SIMPLE: Simple estimator (>= 7 dB)
• SNR_EST_SKEW: Skewness-base est (>= 5 dB)
• SNR_EST_M2M4: 2nd & 4th moment est (>= 1 dB)
• SNR_EST_SVR: SVR-based est (>= 0dB)
