Different measurements have been performed to investigate the effect of UWB and radar pulses on the receiver of a digital wireless communication system. First the coupling of UWB and radar pulses into a typical bar antenna usable for the 2.4 GHz ISM band has been measured. Based on the coupling measurements the effects in the baseband of a typical wireless receiver is being investigated for different radar and UWB pulses. Finally a worst-case analysis by using a HF switch is being investigated for a WLAN and Bluetooth system. The results show how possible interferences with different interference durations and interference repetition rates can cause effects on the performance of a wireless communication system.","PeriodicalId":201448,"journal":{"name":"2010 IEEE International Symposium on Electromagnetic Compatibility","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117002856","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}

Analysts attempting to predict cosite EMI are often faced with not only performing accurate simulations that yield useful results when using mixed data types, but also with managing a large amount of disparate data types in a way that allows straightforward predictions to be made and, just as importantly, allowing the accuracy of those predictions to be refined as more data becomes available to improve the description of the systems in the cosite scenario.

According to the physical characteristics of UWB and the victim system, entire physical layer models are set up. Based on the requirements of bit error rate (BER) and receiver sensitivity of IEEE 802.11n, the emission limits of UWB are obtained in the operating frequency band (5.18∼5.805GHz) of 802.11n. Compared with a method based on interference to noise ratio (I/N) criteria, this method reflects the effect of the actual systems, so the conclusion can provide the reference to formulating the frequency spectrum of UWB within the operating frequency band of 802.11n. Besides, we also reveal that IR-UWB should be more strictly regulated compared with MB-OFDM because of its time domain characteristic.","PeriodicalId":201448,"journal":{"name":"2010 IEEE International Symposium on Electromagnetic Compatibility","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128673805","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}

Less attention, however, has been given to whether or not the introduction of EBGs affect the EMI potential of the circuit to couple unwanted energy to neighboring layers or interconnects. In this paper, we show that the bandgap of EBG structures, as generated using the Brillouin diagram, does not necessarily correspond to the suppression bandwidth generated using S-parameters. In fact, we show that the slow modes which typically exist at the edges of the bandgap of periodic structures contribute to increased radiation, even within the suppression band obtained from the S-parameters. We validate this finding using numerical simulation. Based on this work, design guidelines for EBG structures can be drawn to insure not only suppression of switching noise but also minimization of EMI.","PeriodicalId":201448,"journal":{"name":"2010 IEEE International Symposium on Electromagnetic Compatibility","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117035940","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}
