One-Bit Measurement of the Parameters of Multiple Sinusoids With Unknown Frequency

摘要

This paper introduces a novel procedure for quick estimation of the parameters in a sum of sinusoidal signals based on one-bit measurements. Amplitude, phases and, frequencies of the signal components are assumed unknown, as well as the threshold level of the comparator used to produce measurement results. To provide enough information at the one-bit quantizer input, a sinewave is assumed to dither one of the two comparator's inputs. To ease the procedure's application, only the peak-to-peak amplitude of this dither signal is assumed known.
