Abstract: A rate Detection Apparatus (RDA) includes a power spectral density (PSD) estimator and a rate selector. The PSD estimator is configured to receive samples of a signal, and to estimate a PSD of the signal. The rate selector is configured to identify a transmission rate of the signal responsively to the estimated PSD.

Abstract: A transmitter including a digital-to-analog converter (DAC) to generate an analog output corresponding to a transmitted signal. The transmitter further includes an analog-to-digital converter (ADC) coupled to the DAC. The ADC measures the analog output of the DAC to identify a set of digital samples. The ADC identifies, from the set of digital samples, a set of valid samples, wherein each valid sample has a voltage within a voltage range. The ADC extracts one or more signal properties from the set of valid samples.
