It introduced LDPC channel coding which enables increased spectral efficiency in comparison to turbo codes used in LTE. It also specifies throughputs in the order of tens of Gb/s at lower latencies, putting a challenging constraint on all components in the data chain. In this paper, a parallel high throughput architecture of a joint deinterleaver and derate matcher for 5G NR is proposed. Efficient and scalable nature of the architecture allows easy tuning of throughput versus utilization over a large range of values. Proposed scheme for LLR value storage enables efficient memory utilization with full read and write throughput. The proposed architecture was implemented on a Zynq Ultrascale+ RFSoC FPGA from Xilinx in order to verify the functionality. Implementation achieves clock frequency close to the highest possible on the given architecture. To the best of our knowledge, this is currently the highest throughput implementation available.","PeriodicalId":228464,"journal":{"name":"2021 15th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127334391","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}

Complex and multilayered networks, high-quality signal demands, and strong competition are only some of the aspects that push operators to further optimize their networks. Also, introduction of 5G in their networks enabled mobile operators to offer broad spectrum of 5G services, especially IoT (Internet of Things) and M2M (Machine to Machine) services which further increase traffic volume and the amount of collected data. Traditional data management solutions currently used are not able to successfully respond to such huge amounts of data. Big data technologies represent a modern approach for coping with the enormous data quantities. In this paper, we propose a big data solution that can collect and process huge amounts of data to extract valuable information and help mobile operators to bring their networks to enhanced quality level and offer full IoT solutions to their customers.","PeriodicalId":228464,"journal":{"name":"2021 15th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125296436","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}
