Comparison results show that the electric field strengths around dipole antennas is almost equal to or higher than those of all mobile terminals used in this study for all the considered frequency bands. Consequently, a half-wave dipole antenna can be used for screening test of EMI with medical devices. With respect to mobile terminals, the maximum difference in the electric field strength among all the terminals is approximately 9 and 5 dB for the 800 MHz and 2 GHz bands, respectively. Regarding broadband antenna used in this study, it can be used for screening test of EMI in the frequency bands of 1.5, 1.7, and 2 GHz.","PeriodicalId":6624,"journal":{"name":"2015 9th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":"31 1","pages":"52-55"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74966948","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 paper originates to use the error control coding for more reliability and dependably assurance for such medical data in Medical Network Channel (MNC) system. The establishment of the uplink (UL) / downlink (DL) channels code through the ready existing 3G channel is proposed in this paper. The technique is to use the concatenated error detection and correction code by adding extra channel code in between to work for the medical data only. The new channel is proposed here to use the convolution code by specific technical parameters depending on 3G Standard capabilities and the Bit Error Rate (BER) performance required for transmitting medical data. Our paper comes to prove the results that focusing on using the UL/DL channel for 3G-channel coding. Therefor the paper focused to use the entire UL/DL channel codes in 3G that using convolution code in inside. The adding of BAN connection end to end by using its own standard code has investigated in this paper. The proposed system results has been derived out and analyzed using the computer simulation under different assumed environment channel models such as AWGN, Rayleigh fading and burst noise as well. Resulting to that, the proposal method has improved in term of the error performance BER in whole aspects. The variance between the superior/inferior performances of BER and system complexity has been analyzed in this paper as well.","PeriodicalId":6624,"journal":{"name":"2015 9th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":"80 1","pages":"223-227"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89018343","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}

During the recent years, multiple WUR designs and architectures have been therefore proposed for WBANs and wireless sensor networks (WSN). Superregenerative oscillator (SRO) based architecture is inherently sensitive, which makes it an attractive choice for a WUR. It is known that to improve the selectivity and to reduce the energy consumption the quench frequency should be the same or in the order of data rate. Therefore, synchronization is required. To achieve this with low-power consumption, pulse width modulation is used to encode transferred address information. The decoder measures the pulse widths and uses uncertainty interval that enables loose synchronization between the transmitter and the receiver. The decoder is implemented and its power consumption is measured. Decoder operation is verified with simulations using the hardware description language simulator.","PeriodicalId":6624,"journal":{"name":"2015 9th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":"6 1","pages":"209-212"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78531780","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}

In this paper, by investigating parameter adjustment of frequency modulated differential chaos shift keying (FM-DCSK) UWB system, it is observed that there is an interesting problem that different system parameter adjustments may satisfied their application demands under different medical transmission environments. Concretely the system with integral time equaling to chip duration is a good choice for ordinary medical environment with different quality of service (QoS) requirements, where there is proper adjustment value of distance parameter with optimal bit error rate (BER) performance for per signal to noise rate (SNR); while the system integral time equaling to half of symbol period is more suitable for emergency medical environment with same QoS requirements, where a quick and robust communication system is needed to provided prompt information support to doctors and nurses. Given the above, it is obvious that the coverage is not a limitation factor when UWB technology is developed.","PeriodicalId":6624,"journal":{"name":"2015 9th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":"23 1","pages":"162-165"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80960707","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, shape estimation for breast cancers has been remained as a challenge. In this paper, we propose an elliptical shape estimation method by nonlinear least-squares method in order to develop a breast cancer shape estimation using UWB radar technology. We define a regression formula of a nonlinear least-squares method for one cancer considering a two-dimensional (2D) space. We confirm that our method could estimate parameters of an elliptical shape under simple environment using 2D Finite Difference Time Domain(FDTD) calculation. We evaluate the performance of our proposed method under additive white Gaussian noise(AWGN) environment using theoretical signal sets. We could get good results of estimation of 5 elliptical parameters.","PeriodicalId":6624,"journal":{"name":"2015 9th International Symposium on Medical Information and Communication Technology (ISMICT)","volume":"20 1","pages":"134-138"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76201170","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}
