Reduced Complexity SNR Estimation via Kolmogorov-Smirnov Test

Abstract: Two complexity reducing schemes are proposed in this letter for the recently presented Kolmogorov-Smirnov (K-S) test based signal-to-noise ratio (SNR) estimator. The K-S test based SNR estimator can work properly over an extended SNR range for various multilevel constellations with limited signal samples, but involves considerably more add operations as a result for the huge amount of reference signals needed for matching operations. The proposed two complexity reducing schemes explore the order characteristic… Show more

“…The method is advantages in respect to the mean based methods due to the fact that two feature distributions can easily exhibit a large degree of overlapping even though their respective means differ due to the difference in distribution spread. The KS statistic is in essence the supreme of the difference between the distributions sampled from the two condition classes and it can be calculated as [26]…”

“…Ref. [ 21 ] proposes a signal to noise ratio (SNR) estimator based on the K–S test and binary search scheme that reduces a large number of additions. Furthermore, the K–S test is used in a multiple-input multiple-output (MIMO) system for blind identification of spatial multiplexing and Alamouti space–time block code based on the correlation property of adjacent samples in [ 19 ].…”

“…For comparison, the following methods are also exhibited. The M 2 M 4 is shown as a basis for the EVB estimators [ME94], jointly with the Kolmogorov-Smirnov test method [Fu+15]. The method of moments up to the sixth-order statistics M 6 [LM07] is also shown, as it is used as the initialization of the entropy-based NLS problem and to measure the relative kernel variances, as well as the method of moments up to the eight order, namely the M 8 [ÁLM10].…”
