Detailed Description

Interface of a library with a set of code and carrier phase lock detectors.

SNV_CN0 is a Carrier-to-Noise (CN0) estimator based on the Signal-to-Noise Variance (SNV) estimator [1]. Carrier lock detector using normalised estimate of the cosine of twice the carrier phase error [2].
