In addition, for the most unfavorable value of the relative error, the absolute current error is less than 1 µA. Given that the GPON operates between -7 dBm and +2 dBm, the most meaningful input power values are those at higher levels of optical power. keywords: current; data; dbm; devices; energy; fiber; fig; gpon; load; photodiode; pmu; power; storage; table; value; voltage cache: ietc-56.pdf plain text: ietc-56.txt item: #32 of 44 id: ietc-6 author: Ferreira, Artur; Oliveira, Arlindo; Figueiredo, Mario title: LEMPEL-ZIV SLIDING WINDOW UPDATE WITH SUFFIX ARRAYS date: 2013-06-27 words: 5037 flesch: 68 summary: The lin- ear time SA construction algorithm SA-IS In contrast, encoders based on hash tables or trees encoders, usually require al- locating a maximum amount of memory. keywords: algorithm; compression; data; dictionary; encoding; memory; suffix; time cache: ietc-6.pdf plain text: ietc-6.txt item: #33 of 44 id: ietc-63 author: Sousa, Marco; Vieira, Pedro; Queluz, Paula; Rodrigues, Antonio title: A Survey on the 5th Generation of Mobile Communications: Scope, Technologies and Challenges date: 2018-12-21 words: 10381 flesch: 58 summary: [54] E.
