Abstract
Approaches provide for determining spectral information for a communications signal, such as a wideband communications signal. For example, a communications signal (e.g., a wideband signal) is received at a set of analog-to-digital converters (ADCs). The output of the ADCs is divided into a set of segments. A center frequency for each segment is determined based on the segment bandwidth and a number of segments in the set. The segments can be filtered, buffered, and analyzed using at least one digital signal processing technique (e.g., Fast Fourier Transform (FFT) technique to generate a representation of the segments in the frequency domain. Thereafter, the spectrum of frequency components (i.e., the frequency-domain representation) of the segments can be used to determine the power spectral density of the communications signal for different resolutions based on a resolution mode of the system or other criteria of the system.
