Terahertz wave was generated and modulated with photonic technologies in the transmitter, allowing us to use radio on fiber system concept as well. For the receiver, we used a Schottky barrier diode detector integrated with a planar antenna. With the link, error free data transmission at 12.5 Gbps was experimentally demonstrated. Taking the performance margin of the transmitter and receiver into consideration, we believe that even up to 20-Gbps data can be transmitted.","PeriodicalId":370693,"journal":{"name":"2010 IEEE International Topical Meeting on Microwave Photonics","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129076157","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 centralized signal processing is one of features of the Radio-on-Fiber distributed antenna application. This paper proposes a link quality based antenna selection in Radio-on-Fiber ubiquitous antenna system. In this system, the channel state information is gathered by the centralized control station (CCS). Proposed scheme selects an antenna element with high SNR for multi-user (MU-) MIMO parallel transmission at outdoor radio propagation channel in the presence of shadowing. Proposed scheme improves BER performance with suppressing SNR gap among received MIMO signals compared with the system without using RoF remote antenna.","PeriodicalId":370693,"journal":{"name":"2010 IEEE International Topical Meeting on Microwave Photonics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131962117","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}

We propose and experimentally demonstrate a simple, low-cost method to generate UWB pulses in optics. Unlike other methods, we use the minimal hardware configuration (source/modulator/photodetector) without requiring RF pulse shaping. A novel combination of data and a sinusoidal signal modulates the intensity of a continuous wave laser to create various UWB pulses. For impulse radio UWB, on-off keying (OOK) or phase-shift-keying is accomplished simply by adjusting the data and the sinusoidal signal amplitudes. Multiband UWB signals with OOK can also be realized by this technique.","PeriodicalId":370693,"journal":{"name":"2010 IEEE International Topical Meeting on Microwave Photonics","volume":"2011 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128058945","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 utilization of optical comb enables to scale multi tap filters to large number of taps. By using optical line-by-line pulse shaping to program tap weights, we shape the filter's bandpass. In contrast to our previous work, we demonstrate a much simplified technique based on intensity modulator biased at its minimum transmission which results in double sideband with carrier suppression. We use a programmable optical delay line to uniformly tune the bandpass filter center frequency uniquely across half of the free spectral range. Our new scheme is very simple and easily implementable which provides filters with arbitrary tap weights. As an example we implement a filter with Gaussian apodized tap weights which we tune over 0–5.2 GHz with sidelobe suppression in the range 26–31 dB.","PeriodicalId":370693,"journal":{"name":"2010 IEEE International Topical Meeting on Microwave Photonics","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128347951","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}
