It is a form of multi-carrier modulation technique. One major disadvantage of OFDM is that the time domain OFDM signal leads to a high peak-to-average power ratio (PAPR). In this paper we propose a new selective tone reservation (STR) algorithm for reducing the PAPR in downlink channel of base station. We simulate the STR for different application scenarios with consideration of 4G/5G requirements. Simulation results show the STR has a PAPR reduction performance much better compared with all traditional methods in that it doesn't require any side information and has no effect on the performance of high order modulation users. Proposed method is fast and has an ultra-low latency compared with well-known iterative methods of tone reservation and constellation extension. Its performance is higher compared with a common clipping and filtering due to employing a constellation recognition technique for blind detection of the modulation order. STR fully fits in 4G/5G standard requirements and its complexity doesn't require a huge computational resources.","PeriodicalId":251688,"journal":{"name":"2017 IEEE International Workshop on Signal Processing Systems (SiPS)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125243100","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 main body is a variational Bayes — hidden Markov model (VB-HMM) speaker diarization system. The VB-HMM speaker diarization system avoids making premature hard decision and takes advantages of soft speaker information in an iterative way. Thus, it outperforms most of mainstream speaker diarization systems. Unfortunately, this system is sensitive to its prior in some cases. Either a uniform prior or a flat Dirichlet prior may fail and lead to poor results, thus a more robust and informative prior is desired. Another speaker diarization branch is an i-vector — probabilistic linear discriminant analysis — agglomerative hierarchical clustering (Ivec-PLDA-AHC) system. Benefits from the excellent performance of the Ivec-PLDA system in the speaker recognition field, the Ivec-PLDA-AHC speaker diarization system is believed to be more powerful to cluster segmental i-vectors according to their speakers. Inspired by this feature, we take the output of the Ivec-PLDA-AHC as the VB-HMM's prior. Experiments on our collected database show that the proposed system is significantly better than both of the mentioned systems.","PeriodicalId":251688,"journal":{"name":"2017 IEEE International Workshop on Signal Processing Systems (SiPS)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127724334","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}

Moreover, as they evolved to a point where Gigabytes of memory are required for their operation, we have reached a stage where it becomes fundamental to understand how their inference capabilities can be impaired if data elements somehow become corrupted in memory. This paper introduces fault-injection in these systems by simulating failing bit-cells in hardware memories brought on by relaxing the 100% reliable operation assumption. We analyze the behavior of these networks calculating inference under severe fault-injection rates and apply fault mitigation strategies to improve on the CNNs resilience. For the MNIST dataset, we show that 8x less memory is required for the feature maps memory space, and that in sub-100% reliable operation, fault-injection rates up to 10−1 (with most significant bit protection) can withstand only a 1% error probability degradation. Furthermore, considering the offload of the feature maps memory to an embedded dynamic RAM (eDRAM) system, using technology nodes from 65 down to 28 nm, up to 73∼80% improved power efficiency can be obtained.","PeriodicalId":251688,"journal":{"name":"2017 IEEE International Workshop on Signal Processing Systems (SiPS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125711852","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}

For example, the sub-optimal linear detection schemes, such as zero forcing (ZF) detector and minimum mean square error (MMSE) detector, always have to balance the performance and complexity resulted from the large-scale matrix inversion operations. Recently, some iterative linear solvers, such as conjugate gradient (CG), have been proposed to address this issue. These series of detection algorithms offer a better tradeoff between error-rate performance and computational complexity by avoiding the computation-hungry operations like matrix inversion. However, when the the system loading factor ρ goes up, their results are no longer satisfactory. To solve the aforementioned issues, this paper 1) first introduces a novel, low-complexity pre-conditioner by exploring the properties of the equalization matrix and 2) then proposes a split pre-conditioned conjugate gradient (SPCG) method to speed up the convergence rate of detection. Both analytical and numerical results have demonstrated the performance and complexity advantages of the proposed algorithm over the sate-of-the-art ones. The proposed detector outperforms the conventional CG detector with around 2 dB for BER = 10−4. When the number of user antennas is relatively large, its complexity is only 25% of the existing pre-conditioned conjugate gradient detector based on incomplete Cholesky decomposition (ICCG).","PeriodicalId":251688,"journal":{"name":"2017 IEEE International Workshop on Signal Processing Systems (SiPS)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131949495","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 self-interference stems from the nonlinear behaviour of the passive RF components at the transmitter, which results in passive intermodulation terms that in some cases fall onto the RX band. Moreover, also the individual PAs distort the CCs in a nonlinear fashion, which means that the self-interference is in fact produced by a cascade of two nonlinearities. This is something that has largely been ignored in earlier literature. Hence, in this work, a signal model is derived that considers both the nonlinearity of the PAs and the passive components, resulting in a highly efficient digital cancellation solution. Using realistic waveform simulations, it is shown to outperform the existing digital cancellers that neglect the PA-induced nonlinear distortion. Also the computational complexity of the proposed digital canceller is analyzed in detail. All in all, the findings indicate that the developed digital cancellation solution is a feasible option for improving the receiver sensitivity of mobile devices utilizing inter-band carrier aggregation.","PeriodicalId":251688,"journal":{"name":"2017 IEEE International Workshop on Signal Processing Systems (SiPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130772460","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}
