The circuit uses the standard 0.18 μm CMOS process. The simulation results indicate that the temperature range is -20°C to 80°C and the temperature coefficient (TC) less than 27 ppm/°C is achieved at all process corners. Line regulation is better than 0.045%/V and the power supply rejection ratio in low frequency is close to 56dB. The supply voltage of the proposed bandgap reference ranges from 1.8V to 3.5V while the maximum supply current is 36μA at room temperature.","PeriodicalId":403184,"journal":{"name":"2015 IEEE 9th International Conference on Anti-counterfeiting, Security, and Identification (ASID)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115615483","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}

Via MLD, the negative effects of short cycles limited in the Hamming block can be eliminated. Simulation results show that, up to 2 dB coding gain can be obtained for GLDPC code, with faster convergence rate, in comparison with the counterpart standard code, at BER of 10-7 in Rayleigh fading channel. Even compared with the standard LDPC code which has no 4-cycles, the better behaviors for GLDPC code, with still faster convergence rate, are achieved in several limits.

By using the ADS Channel Simulator and taking advantage of the frequency and impulse responses, the high speed backplane channel is analyzed at first. Then various equalization architectures including the high frequency boost values of linear equalizer (LE) and tap coefficients of decision feedback equalizer (DFE) are analyzed in detail. It is shown that much better performance can be obtained by using some combined LE/DFE compared to using LE or DFE separately, and the cost is only a little increase in complexity.","PeriodicalId":403184,"journal":{"name":"2015 IEEE 9th International Conference on Anti-counterfeiting, Security, and Identification (ASID)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133026743","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}

When a user equipment appears in the monitored area, the system continuously intercepts WiFi beacon messages which are periodically issued by the user's equipments for finding accessable WiFi access point (AP). The system then infers the user's trajectory based on the MAC address and received signal strength indication (RSSI) indicated in the beacon message. We propose an estimation method to match the received electronic signal series along a user's trajectory to the most possible one of the predefined paths. The method mainly uses the variance of RSSI to determine the user pedistrian path. We develop a system prototype and conduct extensive experiments in real experimental environment. The experimental results show that the success rate is up to 68%, which proves that the method is applicable. Our tracking system can be widely applied in miscellaneous public spaces for a variety of applications, e.g., public park navigation.","PeriodicalId":403184,"journal":{"name":"2015 IEEE 9th International Conference on Anti-counterfeiting, Security, and Identification (ASID)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124552086","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}

The collection of RF information can be automatically accomplished with the minimization of drive testing (MDT) in long term evolution (LTE) networks.

We employed the proposed algorithm in LTE cellular networks including rural, urban and Hetnet cases.

In order to forecast the energy efficiency over data rates, which is defined as power dissipation divided by the corresponding data rate, a reference circuit meeting some major features is established, whose energy efficiency functions as the start point of the scaling process. By exploring the relationship between the scaled circuits working at different data rates and the reference circuit, the energy efficiency model is obtained. With this equation-based model, the energy efficiencies of the scaled CTLEs with different boost values are estimated in both CMOS 180-nm process and 90-nm process. Simulation results are given and analyses show that the model is accurate, model results are very close to SPICE simulation results.","PeriodicalId":403184,"journal":{"name":"2015 IEEE 9th International Conference on Anti-counterfeiting, Security, and Identification (ASID)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122028868","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, it also brings a new problem that the full-duplex node will generate a strong self-interference signal. And to deal with the self-interference signal, using existing negative self-interference cancellation and analog self-interference cancellation technology are not enough, effective digital self-interference cancellation is needed for further cancellation. This paper proposes an optimized adaptive algorithm of digital self-interference cancellation based on improved variable step. By using a iteration threshold, we establish a new nonlinear relationship between the step factor and the error signal, which overcomes the slow change problem when the error signal is getting closed to zero, and accelerates the convergence rate.","PeriodicalId":403184,"journal":{"name":"2015 IEEE 9th International Conference on Anti-counterfeiting, Security, and Identification (ASID)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121107930","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}
