However, AMC is vulnerable to the frequency offset. Previous works treat the frequency offset as a constant while the frequency offset is a stochastic variable in some communication systems. Thus in this paper, we propose an unsupervised clustering based method, termed as Clustering based Dynamic Identification(CDI), which can blindly identify signals with stochastic frequency offset. First, we locate one of the cluster centers in constellation through hill-climbing method. Then the modulation order is derived via calculating the number of signals in the certain section. We adopt the clustering method to identify the modulation type. Different from traditional clustering methods which use the Euclidean metric, our specially designed metric is adopted in CDI to diminish the influence of stochastic frequency offset. Finally, experimental results based on hardware measurement verify that our method outperforms than previous methods. It is shown that the Bit Error Rate (BER) for classification decreases by 0.98% for 16QAM and 1.16% for 8PSK, compared with the k-means method.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122735617","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}

Using machine learning algorithms more potential information may be obtained from the user-related data that can play a pivotal role in automatic resource management enabling self-organizing networking (SON) in 5G networks. This paper proposes an energy efficiency (EE)-oriented self-optimization function based on proactive predictions in a multi-cell massive multiple-input multiple-output (MIMO) network. Our self-optimization function can automatically adjust the active antennas in each cell based on the predicted quantity of users in the next time interval to proactively adapt to the fluctuations in the traffic load. Furthermore, a two-step optimization scheme is proposed. The first-step independent optimization scheme employs the single-cell proactive prediction result to obtain the appropriate number of active antennas in each cell to maximize EE. The second-step joint optimization scheme employs multi-cell information related to the number of active antennas and users to further optimize the network. We use a real dataset from existing base stations (BSs) to test our prediction model and optimization schemes. The simulation results demonstrate that both schemes can yield a considerable performance improvement in EE compared with the static antennas adjustment scheme.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127857463","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}

Therefore, it is a hot-spot to research how to reduce the feedback overhead. It is considered that massive MIMO channel is sparse and in actual situation the sparsity is unknown, so the sparse adaptive matching pursuit (SAMP) algorithm is introduced to cope with these problems. Aiming at solving the shortcomings of SAMP, including the fixed step size and too much iterations, the modified SAMP (M-SAMP) is proposed in this paper. We combine the signal segmenting, the initial sparsity estimating and variable step size to reconstruct the signal quickly and accurately. The simulation results show that M-SAMP is superior than the SAMP algorithm both in reconstruction accuracy and computation time. In addition, compared with the orthogonal matching pursuit (OMP), subspace tracking (SP), and SAMP algorithms, the better normalized mean squared error (NMSE) performance of M-SAMP could be witnessed, which demonstrates the practicability of M-SAMP in massive MIMO systems.","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125964838","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}

However, this directional transmission complicates initial access (IA) for mmWave communications. In this paper, we formulate the blind base station (BS) discovery and synchronization in IA process as a bivariate hypothesis detection test, and then propose a reliable and effective detection scheme under non-cooperative reception for mmWave cellular networks. In the scheme, three scanning modes are introduced to intercept signal, namely single-fixed direction scan, polling direction scan, half-direction scan. We derive two different detectors based on energy and correlation, respectively. Through analyzing the test statistics at different delays, the BS time offset is estimated coarsely at UE receiver. Simulation results show that the detection performance of our proposed detectors for mmWave BS discovery is close to the theoretical analysis, and the polling direction scan is more accurate and reliable for mmWave system with narrow beams at low signal-to-noise ratio (SNR).","PeriodicalId":170216,"journal":{"name":"2018 IEEE/CIC International Conference on Communications in China (ICCC)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131622079","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}
