This employs multiple receive antennas to mitigate the channel fading. Partial decisions are first made by employing the conventional energy detector at each antenna, based on which a final decision on the presence of the signal is reached. Performance of the proposed and conventional energy detection schemes is presented in terms of the complementary receiver operating characteristic (ROC), when considering a Suzuki channel. The effect of the sensing duration and mobile speed on the sensing performance is also investigated.","PeriodicalId":153464,"journal":{"name":"2009 Canadian Conference on Electrical and Computer Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128941982","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}

A new adaptive parameter called spacetime symbol rate is applied in our design. We have studied the statistics of signal-to-interference-noise of a linear MMSE receiver over a Rayleigh fading channel. The average BER for a given constellation using the MMSE receiver is calculated numerically. With the statistics as a guideline, two adaptive techniques using constellation and space-time symbol rate are studied, respectively. If constellation and space-time symbol rate are considered jointly, more selection modes can be available. Theoretical analysis demonstrates that the average transmission rate of the joint adaptation can be improved in this case. Simulation results are provided to show the benefits of our new design.","PeriodicalId":153464,"journal":{"name":"2009 Canadian Conference on Electrical and Computer Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130902697","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}

Therein the lack of optical memory is sidestepped by advanced signaling protocols that cannot, however, prevent contentions. The contention probability is highly related to the traffic profile in the core network for which the Engset model has been shown relevant. In OBS, as the data plane is transparent, the traffic profile in the core network is completely defined by the emission process. In this paper, we describe the emission process and identify configurations that take advantage of the Engset model. We then propose a hybrid architecture that features burst re-aggregation in some intermediate nodes to exploit the favorable emission configurations. This variation of OBS requires only a slight modification of the core nodes and significantly impacts the performances: Simulations performed on the EONET network show a significant loss rate reduction, whereas the delay is in the worst case slightly increased.","PeriodicalId":153464,"journal":{"name":"2009 Canadian Conference on Electrical and Computer Engineering","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131398150","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 PCS for grid connection of the PMG-based system requires a rectifier, boost converter and a grid-tie inverter, while the WRIG-based system employs a rectifier, a chopper and an external resistor in the rotor side with the stator directly connected to the grid. Reliability of the PCS is analyzed for the worst case scenario of maximum conversion losses at a predetermined wind speed. The analysis reveals that the Mean Time Between Failures (MTBF) of the PCS of a WRIG-based small wind turbine is much higher than the MTBF of the PCS of a PMG-based small wind turbine. The investigation is extended to identify the least reliable component within the PCS for both systems. It is shown that the inverter has the dominant effect on the system reliability for the PMG-based system, while the rectifier is the least reliable for the WRIG-based system. This research indicates that the WRIG-based small wind turbine with a simple PCS is a much better option for small wind energy conversion system.","PeriodicalId":153464,"journal":{"name":"2009 Canadian Conference on Electrical and Computer Engineering","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123989372","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}
