Erratum to “confluent prony approximation”

On the Accuracy of Solving Confluent Prony Systems

In this paper we consider several nonlinear systems of algebraic equations which can be called “Prony-type”. These systems arise in various reconstruction problems in several branches of theoretical and applied mathematics, such as frequency estimation and nonlinear Fourier inversion. Consequently, the question of stability of solution with respect to errors in the right-hand side becomes criti...

signal specific successive approximation analog to digital converter

چکیده: در میان انواع متفاوتی از مبدل های آنالوگ به دیجیتال که تا کنون معرفی شده اند، مبدل های آنالوگ به دیجیتال تقاریب متوالی(sar ) به علت سادگی ساختار و همچنین توان مصرفی کم، همواره یکی از پرکاربرد ترین مبدل های آنالوگ به دیحیتال در کاربرد های بایومدیکال بوده اند. به همین دلیل تاکنون روش های متعددی برای کاهش هرچه بیشتر توان مصرفی در این مبدل ها ارائه شده است که در اکثر آنها توجهی به مشخصات سی...

Sparsity according to Prony, average performance analysis

Finding the sparse representation of a signal in an overcomplete dictionary has attracted a lot of attention over the past years. Traditional approaches such as Basis Pursuit are based on relaxing a nonconvex `0-minimization problem [1]–[3]. In [4], a new polynomial complexity algorithm, ProSparse, is presented. ProSparse solves the sparse representation problem when the dictionary is the union...
