Typically, UWB was candidate to deliver home connectivity, sensor networks and body area networks. As UWB enabled devices operate in unlicensed mode, standardization efforts have been carried out in different parts of the globe to regulate their use in different contexts. ECMA-368 is an industry led standard for high data rate UWB communications. One of the key managing features of this standard is the so called distributed beaconing. In this paper, we analyze the distributed beaconing mechanism of ECMA-368. We focus on the transient phase in which newcomer devices attempt to join a network by accessing the standard defined beacon period. The joining procedure with which devices access the network is modeled by means of an embedded absorbing Markov chain. The relevant issue of modeling the miss-detection of beacon frames transmitted over fading channels is also assessed. Performance evaluation of distributed beaconing is given in terms of energy consumption. The required overhead for network setup is also analyzed.","PeriodicalId":143107,"journal":{"name":"2011 IEEE International Conference on Ultra-Wideband (ICUWB)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127256521","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}

To benefit from these excellent advantages without using ultra-wideband analog delay lines, in this paper, a finite-resolution digital receiver is proposed. The performance of the proposed receiver is evaluated at a data rate of 114Mbps averaged over 100 realizations of IEEE 802.15.3a channel model 1 (CM1) for different quantization levels of finite-resolution analog-to-digital converters (ADCs) operating at Nyquist rate, taking into account noise, inter-path/pulse interference (IPaI/IPI), and inter-symbol interference (ISI). The effects of sampling rates, number of reference pulses, and the ADC threshold(s), weight coefficient, and summation interval on the receiver performance are also investigated. The evaluation results show that the proposed receivers using finite-resolution ADCs only suffer a performance degradation of several dB as compared to the full-resolution ADC and analog receivers. Therefore, employing finite-resolution ADCs could be a promising approach to implement the WTR receivers without using ultra-wideband analog delay lines.","PeriodicalId":143107,"journal":{"name":"2011 IEEE International Conference on Ultra-Wideband (ICUWB)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122193326","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 next generation of wireless systems will require more than the simple distinction between a LOS and a non-LOS (NLOS) link condition. The future short-range wireless communication and localization systems will require an exact environment identification in order to better set up all the services which the users require with a specific quality level. In this paper a new method for environment identification is proposed. This method is able to identify not only the LOS/NLOS condition but also the environment typology, i.e., if the propagation condition is typical of an office or a residential or an industrial area or outdoor, etc. If the environment in which the transmitter and the receiver are immersed is known, two main advantages can be reached: first, the localization of all the users is more accurate and, secondly, each receiver can be correctly configured in order to best adapt to the propagation conditions (cognitive approach) or to the network conditions (cooperative approach). Unlike the techniques discussed in the literature, the one proposed in this paper does not require any estimation, such as the estimation of the channel parameters. The method proposed here is based on statistical processing of the raw received probe UWB signal.","PeriodicalId":143107,"journal":{"name":"2011 IEEE International Conference on Ultra-Wideband (ICUWB)","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131785978","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}
