Whereas standard approaches such as Kalman filter are of linear quadratic estimation (LQE) type, the technique developed in this paper views system dynamics as a sequence of unitary transformations. The approach consists of two steps: 1. Convert the sequence of vector $mathrm{x}^{(l)}$ observations $l=1ldots M$ to a sequence of localized at $mathrm{x}^{(l)}$ states $vert psi_{mathrm{x}(l)}rangle$. 2. Find unitary operator $mathcal{U}$ ‘optimally converting $vert psi_{mathrm{x}(l+1)}}=vert mathcal{U}vert psi_{mathrm{x}^{(l)}}rangle;$: the problem is reduced to finding the maximum of a quadratic form on $U$ matrix elements subject to constraints that are quadratic forms on $U$ matrix elements as well. The approach is outlier-stable and can be applied to the processes with spikes and non-Gaussian noise. The approach is gauge-invariant, e.g. the result is the same when arbitrary non-degenerate linear transform is applied to input vector $mathrm{x}^{(l)}$ components.","PeriodicalId":141827,"journal":{"name":"2021 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130976033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Iterative hard thresholding (IHT) algorithm and its variants can be considered as a kind of those methods based on gradient descent. Unfortunately, when the objective function has many local minima, the steepest descent typically suffers from being misled into attaining those local minima. One way to facilitate the nonlinear search to be close to the global solution is the manipulation of search step size. In this work, a numerical search is used to find an optimal step size in the sense of minimal signal recovery error for the normalized IHT algorithm. The performance of the proposed step size is compared to that of a randomly chosen fixed one as in the former works. Numerical examples illustrate that the optimal parameters that form up a good step size can provide lower root-mean-square-relative error of the acquired signal than the arbitrary chosen step size method. The performance improvement is obvious for numerous nonzero elements hidden in the sparse signal.","PeriodicalId":141827,"journal":{"name":"2021 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121471392","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The imbalance estimation method makes use of the second-order statistics of the received signals, and a closed-form solution with linear complexity is given by reasonable approximation. The simulation results demonstrate the validity of the proposed scheme, which shows that the method can increase the image reject ratio (IRR) of the signals by more than 45dB, and the scheme is quite robust.","PeriodicalId":141827,"journal":{"name":"2021 International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129146056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
