Given the measurement matrix A and the observation signal y , the central purpose of compressed sensing is to find the most sparse solution of the underdetermined linear system y = Ax + z , where x is the s -sparse signal to be recovered and z is the noise vector. Zhou and Yu [1] recently proposed a novel non-convex weighted ℓ r − ℓ 1 minimization method for effective sparse recovery. In this paper, we reveal that based on ( y, A ), any s -sparse signal can be robustly reconstructed via this method provided that the mutual coherence µ of A fulfills µ < 1 / ( s − 1 + 2 1 =r − 1 s 1 =r ). To our best of knowledge, this is the first mutual coherence based sufficient condition for such approach.","PeriodicalId":50225,"journal":{"name":"Journal of Computational Mathematics","volume":"89 ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139016636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
