The multilayer miniaturized passive components have been designed using meander-line and lumped-distributed approach, and characterized covering IF (2GHz) as well as RF (> 80 GHz) frequencies for a complete system. At the same time compact and high-Q multilayer lumped components have been designed and modeled up to mmW frequency with excellent performance. Lumped element filters have remarkably low pass band loss with high stop band attenuation and miniaturization. These performances are better than most of the reported results from conventional multichip module (MCM) technologies. Further, using a new integration technique, where IC mounting cavities are formed from trench-vias and have precise dimensional control, a mmW modules are realized onto a single substrate integrating MMICs with RF (V-band) SIW components and embedded lumped element (IF) low-pass filter and other passives in bias network with high performance and compactness.","PeriodicalId":225547,"journal":{"name":"2014 IEEE International Wireless Symposium (IWS 2014)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121216712","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 envelope of the modulated RF signal is converted into the pulse train by means of pulse width modulation or delta-sigma modulation. The power amplification of the pulse train can be performed by the highly efficient power amplifiers without the constraint of linearity. The modulated RF signal are restored by low-pass or band-pass filtering of the amplified pulse train. With both high linearity and high efficiency, the pulse-modulated polar transmitter is an excellent candidate for spectrum efficient wireless applications.","PeriodicalId":225547,"journal":{"name":"2014 IEEE International Wireless Symposium (IWS 2014)","volume":"255 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116484971","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 conventional ground plane is replaced by a rectangular ring reflector to form the directional pattern.

In addition, the performance of the proposed antenna is still comparable with the convetional microstrip antenna. The simulated gain is 6.1 dB at the 1.575 GHz, while the back radiation is only -11.6 dB. To verify the proposed design, a protype is fabricated and measured.

In the proposed design, both the transmitter coil set and the receiver coil set are fully planar, comprising of two printed spiral resonator coils and co-planar source and load loops. Comparisons in both quality factor and power transfer efficiency of the design with self-resonant printed spirals and with capacitor-loaded printed spirals are made. In addition, the power transfer efficiency of the planar design with small inductances is also discussed. Measurement results show that the proposed design exhibits a power transfer efficiency of 74.1% at the distance of 200 mm. The planar structure and high transfer efficiency make the proposed design a suitable candidate for wireless power transfer of small portable electronic devices.

The proposed algorithm is based on pseudo-noise (PN) training sequence, and different users employ different PN sequences. To reduce the overhead of the preamble, monocycle pulse is used to modulate one bit information of training sequence. The proposed scheme includes acquisition and timing (fine synchronization) algorithms. Acquisition and coarse channel estimation are firstly gotten. After that, timing and channel estimation can be derived at the same time naturally through energy searching. In multipath channel, no interference among the pulses inner preamble is guaranteed and inter frame interference (IFI) inner one symbol during payload transmitting is allowed. At receiver, demodulation template is derived by combining the channel estimation according to time hopping (TH) code. Correlation detection can be carried out to demodulate the data. Simulation results validate the proposed scheme.","PeriodicalId":225547,"journal":{"name":"2014 IEEE International Wireless Symposium (IWS 2014)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133016076","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 differentiate each RAU, wavelength-division multiplexing (WDM) is an efficient and mostly-used way, but this would require expensive wavelength-specific or wavelength-tunable optical sources. To reduce the cost, colorless or wavelength-independent RAU is highly desirable. In this paper, two approaches to realize the colorless RAUs based on the gain saturation effect or cross-polarization modulation in semiconductor optical amplifiers (SOAs) are reported. Full-duplex radio-over-fiber (RoF) links based on the colorless RAUs are constructed and evaluated.","PeriodicalId":225547,"journal":{"name":"2014 IEEE International Wireless Symposium (IWS 2014)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129982444","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 conventional MIMO approaches, antenna elements are placed far away from each other to eliminate the correlation and make use of the spatial multiplexing. However, this advantage offered by the MIMO comes at the price of losing the beamforming ability in the smart antenna system. We propose a new technique for MIMO communication with active phased antenna array in each transmitter/receiver which we call hybrid phased array MIMO. Coherent processing gain can be achieved by designing a weight vector for each subarray to form a beam towards a certain direction in space. Moreover, the subarrays are treated jointly to form a MIMO system. A four-input-four-output hybrid phased array MIMO system for TD-LTE base station is designed and implemented. The measured results validate the effectiveness of the proposed system.","PeriodicalId":225547,"journal":{"name":"2014 IEEE International Wireless Symposium (IWS 2014)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124410850","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}
