- W3120987288 abstract "This paper addresses the harmonic problem in one-bit linear frequency modulation (LFM) signal recovery. We develop a novel quantization strategy with random thresholds to mitigate the annoying harmonic effect caused by one-bit sampling. The proposed quantization strategy changes the probability distribution of harmonic amplitude. In this case, the average amplitude of each order harmonic is dominated by the probability density function of random thresholds. Therefore, we employ the flexible Beta distribution to approximate various distribution types and then explore the potential optimal distribution of random thresholds. Furthermore, the quantization strategy with the possible optimal random thresholds is introduced into the classical one-bit recovery algorithm to improve the performance. Numerical simulation results demonstrate the effectiveness of our proposed strategy." @default.
