The basic structure of this antenna uses the Fibonacci sequence in the construction of a golden spiral in the first iteration and six hexagonal monopoles are strategically placed in the midpoints of the spiral to maintain the sequence. In addition, the microstrip feed line is partial expanded to implement a notch filter for acquiring ultra-wideband features. The self-complementary sequence engraved in the ground plane allows the smooth current distribution in the radiating patch and the multiple resonant frequencies. In the other hand, the composition and the structure of the proposed antenna guarantees the coexistence of the UWB and WLAN (5.15-5.825 GHz)technologies. The optimized dimensions for this antenna are 30 mm⨯23.3775 mm, with a bandwidth of 2.63 to 11.2 GHz with multiple resonant frequencies at 2.7-3.41-4.14-4.94-6.82-7.98-8.42-9-9.91-10.45 GHz with a VSWR <2 over the entire frequency range except for the rejected frequencies. The compact antenna has a quasi-omnidirectional radiation pattern with suitable input impedance and return loss less than −10dB over the UWB range, these features offer several applications within the telecommunications area.","PeriodicalId":332646,"journal":{"name":"2018 IEEE 10th Latin-American Conference on Communications (LATINCOM)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124855885","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}

For an expected traffic demand, the cost model uses a bottom-up approach for the dimensioning of transponders and optical nodes, namely, reconfigurable optical add/drop multiplexers (ROADM). The infrastructure costs are calculated as the sum of the costs of ROADMs, transponders and optical amplifiers. The approach is applied to the calculation of the network costs for two ROADM implementations, namely, colorless and colorless & directionless. For selected network topologies, the results show that the lowest costs are obtained by colorless ROADMs. However, by this solution the network cannot automatically reroute traffic in case of link failures. This is overcome by adding the directionless property to colorless ROADMs. Although the resulting solution is more costly, it allows efficient utilization of network resources. In fact, a colorless & directionless network reduces the number of transponders needed to serve an expected traffic demand.","PeriodicalId":332646,"journal":{"name":"2018 IEEE 10th Latin-American Conference on Communications (LATINCOM)","volume":"543 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123263920","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}

These systems are subject to signal attenuation due to several atmospheric factors, including rain along the propagation path. Therefore, heavy rainfall tropical regions are affected by a potential increase of system outage probability. On the other side, Multiple-Site Diversity technique appears as a well-known countermeasure that could be applied to mitigate signal degradation in these particular cases. In this work, the performance of Site Diversity in tropical regions is statistically evaluated through simulations derived from the application of Satellite Synthetic Storm Technique (S-SST)to estimate attenuation along the satellite propagation path. The results show important improvements in terms of the reduction in the overall signal attenuation of the system. Finally, the Site Diversity is compared with Time Diversity, other important technique to mitigate satellite signal attenuation due to rain; as a result the storm velocity was assessed and validated.","PeriodicalId":332646,"journal":{"name":"2018 IEEE 10th Latin-American Conference on Communications (LATINCOM)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114555727","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}

Unfortunately, these sensors use multiple standards and are not always designed to work together in a Wireless Body Area Network (WBAN). We studied various applications of the combination of these devices to try and establish an ideal environment which reduces interference and improves data delivery reliability. In this paper we propose a graphical network simulator capable of scaling multiple scenarios, which was tested with a real environment, simulating a WBAN, using five nodes in a ZigBee network where one of them acted as the coordinator and with an approximate overall error rate of ±13.5% in performance metrics such as Packet Delivery Ratio, Link Quality Indicator and Received Signal Strength Indication.

This paper focuses on the design and construction of a smart multi-gas plug-and-play sensor to avoid accidents in smart environments involving CO and LPG. This device is ready to connect on an IoT solution. It uses the standard IEEE 802.15.4 to communicate with a border router responsible to make the data available to other devices. The data will be sent to a middleware granting that other smart devices on the same context can access the information and make the correct decisions.

In this paper, we investigate its use in a Coherent-Optical OFDM transmitter using a Semiconductor Optical Amplifier (SOA) as a power booster. At a fixed bias current, such amplifier may lead to significant nonlinear effects, especially when the signal to be amplified has a non-constant envelope. Thanks to a bias current control scheme, an efficient linearization of the SOA can be achieved. It is shown that the bit error rate (BER) performance of a SOA-based CO-OFDM system can be largely improved by jointly tuning significant key parameters associated with the E T block. A particle swarm optimization (PSO) is applied for identifying the best operating conditions of the ET scheme, which is eventually combined with Peak to Average Power Ratio (P APR) reduction via nonlinear companding. Three distinct scenarios are proposed depending on the tuned parameters. An improvement of up to 8 dB is achieved at a BER of 10–3, for a 5 Gb/s QAM/CO-OFDM transmission.","PeriodicalId":332646,"journal":{"name":"2018 IEEE 10th Latin-American Conference on Communications (LATINCOM)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122139407","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}
