One of the challenges for the implementation is a communication bottleneck in the uplink communication from devices to FL server. To address the issue, many researches have been studied on the improvement of communication efficiency. In particular, analog transmission for the wireless implementation provides a new opportunity allowing whole bandwidth to be fully reused at each device. However, it is still necessary to compress the parameters to the allocated communication bandwidth despite the communsication efficiency in analog FL. In this paper, we introduce the count-sketch (CS) algorithm as a compression scheme in analog FL to overcome the limited channel resources. We develop a more communication-efficient FL system by applying CS algorithm to the wireless implementation of FL. Numerical experiments show that the proposed scheme outperforms other bench mark schemes, CA-DSGD and state-of-the-art digital schemes. Furthermore, we have observed that the proposed scheme is considerably robust against transmission power and channel resources.","PeriodicalId":187645,"journal":{"name":"MILCOM 2021 - 2021 IEEE Military Communications Conference (MILCOM)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129716251","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 date, the majority of papers on this subject apply the null regions to the narrow band, side lobe cancellation of the auto-ambiguity function for a radar echo pulse. By selectively placing a null region in an original waveform's WBAAF, a transmit sequence, especially a white noise radar pulse, can be tailored to lower the energy of peak regions on the WBAAF surface that might be masking desirable portions. The approach discussed in this paper is a unique iterative algorithm which we have termed the Wideband Nulling Algorithm. The Wideband Nulling Algorithm operates on time-scaled data and thus inherently utilizes a wideband approach to placing a null in the ambiguity function surface. Since the algorithm operates on the time domain series, it maps an original waveform to a new time domain waveform such that its second order statistics have a WBAAF surface containing the desired null regions. The goal is to perform this mapping operation with minimal disturbance or impact to the original signal so that the signal content or message is not disturbed. This Wideband Nulling Algorithm is an elegantly simple, mathematical process to reduce interference clutter peaks from a radar, sonar, or an ultrasound ambiguity function surface. This fundamental process has potential applications to many fields including biomedical imaging.","PeriodicalId":187645,"journal":{"name":"MILCOM 2021 - 2021 IEEE Military Communications Conference (MILCOM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129717248","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}

Today, a multitude of DoD networks exist as stovepipes with disparate networking architectures, cybersecurity requirements, management and control tools. We believe that Internet Protocol convergence becomes insufficient to achieve interoperability in the military mission networking context. As the future battlespace involves multiple domain capabilities and assets that must be assembled within mission relevant timelines, operate in unison, and be adaptive to battlespace, a new model is needed to deliver high performance multi-mission and multi-domain data transport. The Flexible Network Interface (FNI) is a robust integration framework that deploys enabling technologies to operationalize heterogeneous networks (DoD and commercial). It delivers consistent end user experience, architecture resiliency, and optimized performance; leveraging heterogeneous host networks and commercial managed services across space, air, ground, and sea. This paper provides an overview of the USSF SSC FNI concept, which is being matured through a series of capability prototyping and demonstration initiatives. We describe the FNI framework's design considerations, and its associated architecture instantiations, key functional elements and interfaces. Several important technology requirements are highlighted, which motivate targeted research and development. Finally, the paper summarizes future work to address open issues across technology, standards, implementations, and deployment.","PeriodicalId":187645,"journal":{"name":"MILCOM 2021 - 2021 IEEE Military Communications Conference (MILCOM)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127881452","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}

However, with the shift towards the wideband regime due to the crowded frequency spectrum, the high cost of obtaining channel state information in this regime impedes the usage of code division multiple access. Impulsive frequency shift keying is a modulation scheme that performs well in the wideband regime without channel state information, and has potential for low probability of intercept systems due to it being based on frequency shift keying. In this work, we demonstrate the concept of impulsive frequency shift keying with over the air testing. We consider the performance of impulsive frequency shift keying in Rayleigh fading channels with both log-normal path loss and shadowing to facilitate the development of a link budget for the transmitter and receiver design. Its performance is investigated in the real world by implementing the transmitter and receiver using software-defined radios and performing over the air tests in a suburban environment by fixing the transmitter and attaching the receiver to a moving vehicle. We achieve a data rate of 0.9 kb/s, which is sufficient for text communications, and show that the symbol error rate for discretized signal-to-noise ratio bins follows a similar trend to the probability of a symbol error in the simulations.","PeriodicalId":187645,"journal":{"name":"MILCOM 2021 - 2021 IEEE Military Communications Conference (MILCOM)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115263454","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}
