Coherent distributed antenna arrays require accurate phase, frequency, and time alignment. However, each node in the distributed array generates its frequency using independent oscillators, and thus without appropriate frequency synchronization the emitted signals will not appropriately cohere. In this paper, we present a one-way frequency transfer approach that uses a self-mixing circuit architecture in a master-slave synchronization architecture. The master node transmits a multi-tone signal that consists of two tones separated by a 10 MHz frequency reference. The self-mixing circuit receives and demodulates this signal by splitting it and then passing it to the radio-frequency (RF) and local oscillator (LO) terminals of a mixer. The resulting signal is filtered to retain only the 10 MHz modulation, which is used to discipline the oscillator on the slave node. We present experimental results using software-defined radio, showing wireless synchronization via a cabled distributed beamforming experiment at 1.5 GHz.","PeriodicalId":6784,"journal":{"name":"2020 IEEE/MTT-S International Microwave Symposium (IMS)","volume":"93 1","pages":"1137-1140"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77350983","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}

To this end, three different learning algorithms - sign, signed regressor, and sign-sign - are formulated for the LUT-based DPD models, such that the potential rank deficiencies, experienced in earlier methods, are avoided. Then, extensive RF measurements utilizing a state-of-the-art mmW active antenna array system at 28 GHz are carried out and reported to validate the methods. Additionally, the processing and learning complexities of the considered methods are analyzed, which together with the measured linearization performance figures allow to assess the complexity-performance tradeoffs.
