In 60 GHz millimeter wave (mmWave) wireless systems, orthogonal frequency division multiplexing (OFDM) scheme can provide high data rate over than 6 Gbps; however, the high peak-to-average power ratio (PAPR) of OFDM signals will reduce the power efficiency of the power amplifier (PA). Digital predistortion (DPD) methods were proposed to compensate the nonlinearity and to improve the power efficiency of the PA; as well as dual-band concurrent DPD was proposed to simplify the RF circuit of the transmitter. However, the low oversampling rate in the baseband of the mmWave channels lets it become a difficult task. In this paper, we evaluate a dual-channel DPD scheme for 60 GHz band mmWave OFDM systems with a cascade 3-box nonlinear PA model that can represent the memory effects of the PA. In the simulation results, at the back-off of 6 dB, error vector magnitudes (EVM) of the channels are improved more than 9 dB and 11 dB in the passbands of channels with DPD compensation up to the 3rd and 5th order, respectively.","PeriodicalId":185971,"journal":{"name":"2016 IEEE MTT-S International Wireless Symposium (IWS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128320648","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 paper, we propose a personalized eco-friendly route search method that considers the driver's driving style, road traffic, geographic information and vehicular parameters. Firstly, we classify the driving styles into three categories (calm, normal and aggressive) by adopting a Learning Vector Quantization (LVQ) neural network with inputs based on 16 characteristics related to vehicle speed, acceleration and engine speed. Secondly, we design a roadway traffic estimation model based on functional similarity and congestion propagation characteristics. Thirdly, we propose a model for fuel consumption estimation (FCE) based on multivariate nonlinear regression to accomplish the eco-friendly route search. To evaluate our route search method, we conducted experiments using real-world vehicle data gathered in the city of Beijing. Our experimental results show that the proposed route search method can achieve a driving-style prediction accuracy of 82.17%, and can reduce the fuel consumption by 16% as compared to the time-priority routes.","PeriodicalId":185971,"journal":{"name":"2016 IEEE MTT-S International Wireless Symposium (IWS)","volume":"694 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116100670","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}

A discussion of the salient points from circuit implementation perspective is also done in detail. Mainly, the performance metrics that are prioritized for 160MHz IEEE 802.11ac and single carrier IEEE 802.11ad are highlighted; a placement method suited for a FIR DAC is covered and some of the limiting factors associated with the method are also detailed.
