OFDM serves to convert frequency-selective MIMO channels into equivalent or parallel flat MIMO channels, thus decreasing the complexity at the receiver, while simultaneously helping to attain robust high data rate transmission. One of the key challenges faced by researchers in designing a MIMO-OFDM system is how to mitigate Peak-to-Average-Power Ratio (PAPR). The MIMO-OFDM signal can be displayed as the summation of independent complex variables with adjustable phases. When all the variables become in phase a peak of the summation of amplitudes is formed. This leads to amplification difficulties at the transmitter and to high out-of-band radiation in case of non-linear power amplifiers. The nonlinearity arises mainly because of the large input power range into the nonlinear region of the power amplifier. The literature abounds with methods for mitigating PAPR. This paper suggests a useful model for the relation between the input data and output PAPR, and proposes a pre-coding technique model to redistribute the input data. The results shows that the PAPR reduction capability of the pre-coding technique facilitates the MIMO-OFDM system to perform better with a reduced PAPR. Simulation results with BPSK and QPSK modulations exhibit a reduction in PAPR of around 4 $mathbf{dB}$.","PeriodicalId":430928,"journal":{"name":"2018 IEEE 39th Sarnoff Symposium","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133490929","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 main idea is to install in venues, Bluetooth radio transmitters (beacons) that broadcast their identifier to nearby devices. A mobile application runs on user's smart phone, receives beacon identifiers and is capable of estimating its distance from sensors in range. Encoded information is transmitted to the cloud where computation of the desired route takes place. iNaaS service responds with navigation instructions which are displayed on visitors' mobile devices (e.g, smartphones). No personal information is sent to the cloud. Information management, including user profiles, access rights, permanent storage and data processing takes place on the cloud. iNaaS tracks users movements in buildings and offers prompt response on cases of disoriented users. We run an exhaustive set of experiments using simulated (but realistic) data aiming to evaluate both, iNaaS response time and scalability. The results demonstrate that the system can handle large number of users in real time.","PeriodicalId":430928,"journal":{"name":"2018 IEEE 39th Sarnoff Symposium","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121701371","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}

Antenna assignment problem for JALN High Capacity Backbone (HCB) has been studied in [1], [2] where each JALN aircraft has four mounting points for directional antennas. Another resource allocation problem arising is that how we can efficiently assign the frequencies to JALN HCB. Two-way traffic through a link is assigned to two disjoint frequency bands. Frequency Division Multiplexing Access (FDMA) is used to share bandwidth and avoid the interference among multiple transceivers on a single aerial platform. Two Frequency Assignment Problems (FAP) are considered in this work, which are called MMC-FAP and MS-FAP. MMC-FAP is to Minimize the frequency usage of the Most Congested aerial platform while accommodating the offered traffic demands and without violating the frequency constraints. MS-FAP is to Minimize the frequency Span in both frequency bands. By exploiting problem-specific properties, MMC-FAP can be formulated as a Mixed Integer Linear Programming (MILP) problem, which has a tight constraint space by explicitly finding all maximal cliques in the conflict graph. Then, binary search strategy is used to find an optimal solution of MS-FAP problem while MMC-FAP occurs as a sub-problem. Numerical experiments are used to show the performance of the proposed approach.","PeriodicalId":430928,"journal":{"name":"2018 IEEE 39th Sarnoff Symposium","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125280937","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}

Spatial modulation (SM) is presently one of the most eminent MIMO techniques. As, it combines the advantages of having higher spectral efficiency than repetition coding (RC) while overcoming the inter-channel interference (ICI) faced by spatial multiplexing (SMP). Moreover, SM reduces system complexity. In this paper, for the first time in literature, the use of MIMO techniques is explored in Internet-of-Things(IoT) deployments by introducing a novel technique called security aware spatial modulation (SA-SM).SA-SM provides a low complexity, secure and spectrally efficient technique that harvests the advantages of SM, while facing the arising security concerns of IoT systems. Using an undemanding modification at the receiver, SA-SM gives an extra degree of technology independent physical layer security. Our results show that SA-SM forces the bit-error-rate (BER) of an eavesdropper to not exceed the range of 10−2, which is below the forward-error-correction (FEC) threshold. Hence, it eradicates the ability of an eavesdropper to properly decode the transmitted signal. Additionally, the efficiency of SA-SM is verified in both the radio and visible light ranges. Furthermore, SA-SM is capable of reducing the peak-to-average-power-ratio (PAPR) by 26.2%.","PeriodicalId":430928,"journal":{"name":"2018 IEEE 39th Sarnoff Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128070435","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}
