Inspired by discrete signal processing, where embedding a line digraph into a cycle digraph facilitates the powerful Discrete Fourier Transform (DFT) for signal analysis, addressing the structural complexities of general digraphs can help overcome the limitations of the Graph Fourier Transform (GFT) and unlock its potential. The DFT functions as a GFT for both cycle graphs and Cayley digraphs defined over the finite cyclic group <inline-formula><tex-math>$mathbb{Z}_{N}$</tex-math></inline-formula>. In this work, we present a systematic framework to identify a class of Cayley digraphs capable of encompassing a given directed graph. By embedding the original directed graph into such Cayley digraphs and employing envelope extensions that inherently support the GFT, we enable the use of the GFT associated with the extended structures for signal analysis. Among the candidate envelope extensions, optimal performance is achieved by selecting one that satisfies a set of pre-specified structural properties. The resulting GFT is numerically stable and provides a basis that approximates the eigenstructure of the adjacency matrix associated with the original digraph. It is shown that the envelope extensions possess a convolution product, with their GFT fulfilling the convolution theorem. Additionally, shift-invariant graph filters (systems) are described as the convolution operator, analogous to the classical case. This allows the utilization of systems for signal analysis.","PeriodicalId":13330,"journal":{"name":"IEEE Transactions on Signal Processing","volume":"73 ","pages":"3598-3613"},"PeriodicalIF":5.8,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145073014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we focus on the CE problem for time-division duplex (TDD) massive MIMO systems, where downlink (DL) and uplink (UL) channels exhibit strong reciprocity. To fully exploit the channel reciprocity, we design a DL-UL collaborative channel sounding scheme that employs a limited number of transmit antennas on both sides to save training overhead. By integrating DL and UL channel measurements with different signal-to-noise ratios into two data-fitting terms, we formulate the CE problem as a downlink-uplink collaborative atomic norm minimization (DUCANM) problem and provide theoretical analysis to select the hyperparameters involved. A partially decoupled atomic norm minimization formulation is proposed to solve the DUCANM problem effectively. To further accelerate the computation of DUCANM, we propose a fast algorithm based on the alternating direction method of multipliers. Numerical simulations are provided that demonstrate the superiority of our proposed method in terms of CE accuracy, training overhead, and running time.","PeriodicalId":13330,"journal":{"name":"IEEE Transactions on Signal Processing","volume":"73 ","pages":"3614-3628"},"PeriodicalIF":5.8,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145035877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
