Since QAM and polarization modulation have different energy efficiency performance in the linear and nonlinear region of power amplifier respectively, thus the optimal energy efficiency can be obtained by combining the two modulation schemes together and adjusting their modulation order adaptively to fulfill the varying data rate requirement. The power series model of power amplifier is used to analyze the effects of both the in-band distortions and the out-of-band emissions on OFDM signals. Based on above, the proposed scheme can be formulated as an optimization problem regarding the output back off value as well as the modulation order of polarization modulation and QAM. Simulations under the same symbol error rate threshold and data rate requirement show that, the energy efficiency of the proposed scheme is nearly twice as that of the traditional QAM scheme in OFDM systems.","PeriodicalId":137845,"journal":{"name":"2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115940400","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 double Rice fading channel is constructed as the product of two independent but not identically distributed Rice processes. In addition, we assume that the double Rice processes affecting the signal received over the L branches of the diversity system are independent and identically distributed. Under these assumptions, and by using the cumulative distribution function (CDF) approach, we derive an expression for the average BEP performance of binary noncoherent frequency-shift keying (FSK) and differential phase-shift keying (DPSK) modulations. The result elaborated is generic in that it includes the propagation environments described by RayleighxRice and double Rayleigh fading models as special cases. The result is in the form of semi-infinite range integrals, that are easy to compute numerically. Additionally, for the special case of dual-branch SC diversity, i.e., L = 2, relatively simplified expressions for the BEP performance are obtained. Moreover, illustrative numerical results are presented together with corresponding simulation quantities to check the validity of the derived analytical quantities, and analyze the impact of the fading parameters on the BEP performance. The results are useful in assessing the performance of amplify-and-forward (AF) dual-hop vehicle-to-vehicle (V2V) communications with line-of-sight (LOS) paths, and where the additive noise in the relay station can be neglected.","PeriodicalId":137845,"journal":{"name":"2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134397522","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}

Without knowing any prior knowledge of the transmitted data, the received signals may be affected by intersymbol interference (ISI), carrier frequency offset, phase offset and timing delay. ISI and these unknown parameters would degrade the performance of many recognition methods. There have been many robust estimators of carrier frequency offset, phase offset and timing delay. However, the robust recognition methods combating ISI have not been well designed. Most blind channel equalization methods, which are designed to overcome the effects of ISI, have poor robustness to noise and carrier frequency offset. In this paper, a robust recognition scheme is proposed to recognize phase-shift keying (PSK) and quadrature amplitude modulation (QAM) signals in non-cooperative communication with ISI environment. The envelope spectrum of PSK and QAM signals are analyzed. Then the recognition scheme based on the ratio of spectral peak to spectral centroid (RSPSC) of envelope spectrum is presented. Such scheme achieves a good recognition performance in the presence of ISI. Spectral centroid is utilized to enhance the robustness to noises. By extracting the envelope spectrum, in addition, the method avoids being affected by carrier frequency offset, phase offset and timing delay. The feasibility of the proposed method has been proved in the respects of theory and simulations.","PeriodicalId":137845,"journal":{"name":"2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129391897","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 transmission of video content even worsens the delivery problem because of the large size and continuous nature of the medium. Therefore, loss concealment is inducted as a part of the solution, alongside other delivery enhancement mechanisms. Loss concealment techniques are usually used Forwards, where the source must spend extra processing and transmission volume to enable the receiver to recover lost data parts. These techniques are not only associated with prolonged latencies and video encoding manipulations, but they are also sensitive to the loss pattern, which might leave the receiver in passive suspension if a key part for recovery was missing. In this work, we propose a Backward loss concealment mechanism, which allows the receiver to react to a certain amount of loss. Missing parts of the scalable video stream are compensated by a composite solution that encloses 1) video frame loss error concealment, and 2) network demands, which are initiated and cast in search for missing parts from other nodes in the network. Simulation-driven experiments prove the applicability of the backward mechanism, with a limited capability depending on the target application requirements.","PeriodicalId":137845,"journal":{"name":"2016 IEEE 27th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130903596","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}
