  Abstract: In this paper, the problem of signal parameter estimation from measurements acquired by a low-complexity analog-to-digital converter (ADC) with $1$-bit output resolution and an unknown quantization threshold is considered. Single-comparator ADCs are energy-efficient and can be operated at ultra-high sampling rates. For analysis of such hard-limiting systems, a fixed and known quantization threshold is usually assumed. In the symmetric case, i.e., zero hard-limiting offset, it is well-understood that in the low signal-to-noise ratio (SNR) regime the signal processing performance degrades moderately by ${2}/{\pi}$ ($-1.96$ dB) when comparing to an ideal $\infty$-bit converter. Due to hardware imperfections, low-complexity $1$-bit ADCs will in practice exhibit an unknown threshold different from zero. Therefore, the offset has to be estimated jointly with the signal parameters. Here we study the estimation accuracy which can be obtained with receive data preprocessed by a hard-limiter with unknown quantization level. In order to characterize the achievable performance, we employ analytic error expressions for different setups while modeling the offset as a nuisance parameter. In the low SNR regime we establish the necessary condition for a vanishing loss due to missing offset knowledge at a receiver with $1$-bit ADC. We then validate our analysis by visualizing the quantization loss under an unknown $1$-bit threshold when wireless intersymbol interference (ISI) channel estimation is performed. Finally, we verify the results by Monte-Carlo simulations of asymptotically optimal estimation algorithms.
