First, a dual-stream transmission scheme under a 2-by-M (M ≥ 2) multiple-input multiple-output scenario is studied. A generalization for any number of simultaneous substreams is then built based on the initial results. We provide an approximation on the average bit error probability (ABEP). We also show that a rotation of π/4 radian applied on the BPSK signal constellation minimizes the derived approximation on ABEP. It is shown that the error performance of the original ZFRBF scheme can be enhanced by exploiting SSD with only an insignificant increase in complexity and no additional use of bandwidth/time slots.","PeriodicalId":183694,"journal":{"name":"2017 Advances in Wireless and Optical Communications (RTUWO)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125791855","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}

High density of remote radio heads (RRHs) deployments results in inefficient energy consumption. Moreover improvements in the battery capacity of mobile devices lag far behind the surging demand for transmit power, which makes power efficient communication an essential requirement for the next generation wireless communication systems. In this paper we consider a network with multiple service providers share the ultra-dense C-RAN (UD-CRAN). We consider the QoS requirement of each service provider and propose power control algorithm. The performance is evaluated through simulations and demonstrated that our algorithm provides significant energy efficiency gains while meeting the given data rate specifications.","PeriodicalId":183694,"journal":{"name":"2017 Advances in Wireless and Optical Communications (RTUWO)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129682531","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}

One of the solutions to overcome this problem is to use a mobile robot that is equipped with, in addition to the sensing unit, an actuator unit that controls its movement. In this case, the mobile robot is considered as a mobile sensor node that has the capability to monitor the uncovered regions in the sensor field. However, the main challenge in this case is how to control the movement of the mobile robot such that the area coverage is maximized and the time required to sample the uncovered regions is minimized. In this paper, we propose a fuzzy logic-based approach that controls the mobile robot movement in the sensor field in order to maximize the area coverage. The inputs of the fuzzy system determine the next point that the mobile node will select when it moves in the sensor field. Simulation results have shown that the proposed approach outperforms the random and standard moving patterns.","PeriodicalId":183694,"journal":{"name":"2017 Advances in Wireless and Optical Communications (RTUWO)","volume":"57 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120920175","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 this contribution a newly developed SVD algorithm for polynomial matrices (PMSVD) is analyzed and compared to the commonly used SVD-based MIMO equalization. Since the PMSVD processing results in independent single-input single-output layers exhibiting a frequency-selective characteristic, a simple zero forcing equalizer or an optimal Viterbi detector is applied in this work so as to remove the occurring inter-symbol interferences. The PMSVD orthogonalization is compared with the conventional SVD in terms of the achievable spectral efficiencies, showing that there is no loss applying PMSVD over SVD processing. In addition, the bit-error rate performances in different channel scenarios are evaluated and optimized by applying combined bit and power allocation schemes. One scenario involves the measured specific impulse responses of a (2×2) optical MIMO channel, consisting of a 1.4 km multi-mode fiber, optical fusion couplers for mode multiplexing and demultiplexing when operating at a wavelength of 1576 nm. The computer simulation results show that the PMSVD could be an alternative signal processing method compared to conventional SVD-based approaches in frequency-selective MIMO channels.","PeriodicalId":183694,"journal":{"name":"2017 Advances in Wireless and Optical Communications (RTUWO)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122152833","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}
