TETRA is comparable in structure to the world-wide successful GSM system, however, individual features of TETRA are different, often more efficient and better designed than in GSM. TETRA is therefore providing an important source for the further development of standards for mobile telecommunications.This volume is timely and one of the first to cover TETRA and related subject areas.FeaturesTETRA (Standard)Mobile communication systemsStandardsDigital communicationsStandardsTETRA (Standard)Mobile communication systemsStandards.Digital communicationsStandards.621.3845621.38450218Dunlop JohnProf.1677516Girma Demessie1677517Irvine James1342012MiAaPQMiAaPQMiAaPQBOOK9910830174403321Digital mobile communications and the TETRA system4044447UNINA03528nam 22007575 450 991048450580332120251107172855.0981-336-478-510.1007/978-981-33-6478-3(CKB)4100000011728420(DE-He213)978-981-33-6478-3(MiAaPQ)EBC6461914(PPN)253253756(EXLCZ)99410000001172842020210121d2021 u| 0engurnn#008mamaatxtrdacontentcrdamediacrrdacarrierBlockchain Technology and Application Third CCF China Blockchain Conference, CBCC 2020, Jinan, China, December 18-20, 2020, Revised Selected Papers /edited by Ke Xu, Jianming Zhu, Xianhua Song, Zeguang Lu1st ed. 2021.Singapore :Springer Nature Singapore :Imprint: Springer,2021.1 online resource (IX, 127 p. 76 illus., 43 illus. in color.)Communications in Computer and Information Science,1865-0937 ;1305981-336-477-7 ChainSim: A P2P blockchain simulation framework -- Blockchain-based Access Control Mechanism in Electronic Evidence -- A Blockchain-Based Digital Copyright Protection System with Security and Efficiency -- Multi-Core and SIMD Architecture based Implementation on SHA-256 of Blockchain -- EduChain: A blockchain-based education data management system -- A Case Study for Blockchain in OTC: “BATN”: A Prototype for Bid and Ask Trading Network -- A Group-based Optimized Practical Byzantine Fault Tolerance Consensus Algorithm -- Storage Optimization for Certificates in Blockchain based PKI System.This book constitutes the refereed proceedings of the Third CCF China Blockchain Conference, CBCC 2020, held in Jinan, China, December 2020.
