The proposed method takes advantage of the interesting property that the ICI which is essential for CoMP can be represented by the communication distance easily obtained from vehicle position information in a 2-cells scenario. Moreover, the proposed approach can be adopted for more than 3 cells by combining the ICI between 2 cells. The proposed method exploits diversity reception in the case of time division multiplexing (TDM), which makes it possible to improve the channel capacity in overlapped area. The effectiveness of the proposed method is demonstrated in comparison with the case of no coordination (w/o CoMP) under the practical scenario based on the taxi radio system in Japan.","PeriodicalId":266973,"journal":{"name":"2017 IEEE Topical Conference on Wireless Sensors and Sensor Networks (WiSNet)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133213330","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}

Near field effects strongly influence the signal characteristics of a reflection of the electromagnetic wave near the antenna, especially if the target is low reflective. In this paper a calibration procedure based on phase error correction by segmental polynomial approximation is proposed that utilizes these effects. After validating the functionality of the calibration algorithm and its improvement by comparison to a comparable state-of-the-art procedure, two further near field measurements are presented. A cardboard as well as a plastic plate are used as low reflecting targets to show the applicability of the proposed calibration procedure for diverse measurement scenarios.","PeriodicalId":266973,"journal":{"name":"2017 IEEE Topical Conference on Wireless Sensors and Sensor Networks (WiSNet)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132938043","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 order to obtain realistic and accurate system simulation results, the model of the six-port demodulator is implemented using the powerful schematic platform of Keysight's Advanced Design System (ADS) and the measured S-parameters of the fabricated six-port. The performances of the six-port based direct conversion receiver model are assessed in terms of various PSK/QAM modulated signals, and Error Vector Magnitude (EVM) for different local-oscillator (LO) and RF power levels.

The system permits the co-location and simultaneous operation of a commercial Bluetooth chipset with a carrier source, enabling the use of specially designed BLE-Backscatter tags to send data to the commercial Bluetooth chipset with no software modifications. This demonstration shows the potential for reusing the wireless chipsets in future full-duplex devices as readers for backscatter tags and other backscatter-based devices. Using a directional coupler-based carrier cancellation implementation, we achieve carrier suppression of 50 dB.

This paper investigates the influence of target geometry and position on the accuracy of its range estimation using a W-band FMCW radar. A relation between target geometry and accuracy is established through Cramér Rao Lower Bound (CRLB). Based on the measurements of different targets, an optimal shape and size is proposed which provides an average accuracy in the single digit micrometer range.

In particular, Doppler radars can be coherently exploited to extract spectrograms—i.e., time-Doppler maps—of industrial-type wind turbines. This work conducts short-range experiments corresponding to a 50-m-height Vestas wind turbine illuminated by two custom-designed quadrature radar prototypes operating at 5.8 and 24 GHz, respectively. It is observed that the obtained experimental radar signatures—that are shaped by flashes and quasi-sinusoidal halos—exhibit distinct characteristics depending on the acquisition geometry and the operation frequency of the radar sensor.
