Microwave is the best solution in urban and sub-urban areas due to low cost and newly provided capacity by microwave links which reaches 10 Gbps. Thus microwave links is a very important aspect in mobile network. Microwave Radio Link design begins by doing the link budget analysis which include specific parameters for the link to operate. Microwave link should be maintained with these parameters to keep acceptable radio performance, capacity and latency. In this work we presented a practical and automated criteria to maintain these parameters as designed without impact on radio performance especially RSL (Receive Signal level).

This work proposes two power allocation algorithms for Conjugate Beamforming (CB) and Zero-Forcing (ZF) pre-coders in downlink scenario. They are based on quantizing the transmitted powers of APs to reduce the system complexity. The performance of the proposed algorithms is evaluated under the most common practical scenarios such as channel errors, pilot contamination and correlated shadowing channel model. The results show that the proposed algorithms have closer solution to the optimal one for both pre-coders. Moreover, ZF pre-coder significantly outperforms CB pre-coder with and without pilot contamination effect under both correlated and uncorrelated shadowing channel models.","PeriodicalId":197824,"journal":{"name":"2018 International Japan-Africa Conference on Electronics, Communications and Computations (JAC-ECC)","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116120457","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}

Although deliberate amplitude peak limiting is a promising PAPR reduction approach, it causes un-desired nonlinear in-band distortion and out-of-band radiation. Thus, the joint use of a peak limiter and band-limitation filter such as clipping-and-filtering (C&F) is required. The objective of this paper is to evaluate the effect of C&F based PAPR reduction for mMIMO-OFDM systems, where a band-limitation filter is designed to limit out-of-band radiation due to clipping while mitigating peak amplitude regrowth due to filtering. We discuss the effect of utilizing extra degrees of freedom for compensating in-band distortion due to C&F in mMIMO systems. Simulation results verified the effectiveness of the above approach in terms of instantaneous peak power, adjacent channel leakage power ratio (ACLR) and signal-to-distortion power ratio (SDR) in mMIMO-OFDM downlink.","PeriodicalId":197824,"journal":{"name":"2018 International Japan-Africa Conference on Electronics, Communications and Computations (JAC-ECC)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124390262","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}

This paper presents a Mobility based Genetic Algorithm Hierarchical routing Protocol (MGAHP) to achieve maximum lifetime of the network and improve the stable period of MWSN. The basic idea of the proposed MGAHP protocol is using Genetic Algorithm (GA) to find the optimum number of Cluster Heads (CHs) and their locations depending on minimizing the energy consumption of the sensor nodes.

The problem encountered with ANFIS usually occurs in the designing process. it includes the setting of various parameters which can be complicated and time-intensive for iterations. Facing this problem, in this paper, a Design of Experiment (DoE) methodology will be used to optimize the significant parameters of ANFIS when it is applied to inverse kinematics solution. Using Response Surface Methodology (RSM), four factors are considered as input variables. Results show that the validation error can be significantly improved using the proposed scheme.

In the SMTs, the indices of the building blocks of the communication system are harnessed in an innovative way to embed an additional information. As such, the SMTs use the transmit antenna indices to fulfill higher transmission efficiency than the other MIMO opponents. Although of their appealing advantages, the SMTs suffer from a main disadvantage which is represented in the logarithmic proportion between their achievable data rates and the number of the transmit antennas. Therefore, the authors proposed the fully-quadrature spatial modulation (F -QSM) in order to vanquish the main disadvantage of the SMTs. In the F -QSM, the transmit antenna indices are varied in an innovative way to achieve a linear proportion between the achievable data rate and the number of the transmit antennas. In this paper, the performance of the F-QSM is investigated over Rician fading channel. The average bit error rate performance (ABER) of the F -QSM is assessed and weighted against the ABER of the conventional SMTs under different values of Rician factor. Furthermore, the computational complexity of the F -QSM is obtained as well and weighted against the computational complexity of the conventional SMTs. The conducted Monte-Carlo simulations substantiate the outweighing of the proposed scheme in terms of achievable data rate and ABER performance but at the expense of a slight increase in the computational complexity compared to the conventional SMTs.","PeriodicalId":197824,"journal":{"name":"2018 International Japan-Africa Conference on Electronics, Communications and Computations (JAC-ECC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129201279","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}
