The DFRC base station sends signals to communicate with the downlink users while detecting a multiple-input multiple-output radar target. The system performance is evaluated by an affine combination between the communication multi-user interference energy and the reciprocal of the radar output signal-to-interference-plus-noise ratio. Then a joint minimization problem of the affine function is formulated, subject to constant modulus constraints. This is a typical nonconvex optimization problem. In the paper, we propose a new online learning network (OLN) scheme to solve it, by setting proper trainable network parameters, formulating a loss function, and selecting a suitable learning rate for the OLN. Simulation results are presented to demonstrate the higher performance for the DFRC system by the proposed OLN method than that by a traditional optimization method.","PeriodicalId":296346,"journal":{"name":"2023 IEEE Statistical Signal Processing Workshop (SSP)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115481965","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 this scheme, denoted by GLIM-OFDM, we investigate the bit-error rate (BER), the mean-square error (MSE) of channel estimation, as well as the Cramer-Rao bound on the latter. Furthermore, we present a novel physical layer security (PLS) technique for the GLIM-OFDM scheme using precoding at the transmitter assuming it has the channel state information (CSI) between the LEDs and a legitimate user, but no knowledge of the CSI corresponding to eavesdroppers. The efficiency of the proposed PLS technique is demonstrated through numerical results.","PeriodicalId":296346,"journal":{"name":"2023 IEEE Statistical Signal Processing Workshop (SSP)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122805819","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 proposed algorithm uses Lorentzian norm as the underlying cost function which provides robustness against heavy tailed noise, e.g., impulsive noise. Analysis is carried out for the proposed algorithm using Majorization-Minimization framework and we show that under proper selection of parameters, the proposed SLIHT algorithm produces a sequence of row sparse estimates for which the Lorentzian norm of the residual is non-increasing. Extensive simulation studies are carried out against state of the art methods and it is observed that performance of the proposed algorithm is better or at least at par with the current methods.","PeriodicalId":296346,"journal":{"name":"2023 IEEE Statistical Signal Processing Workshop (SSP)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128566390","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}

Ultra-wideband impulse (UWB) radar recently became popular because of its ability to sense tiny motions from breathing and cardiac activities. The heartbeat signal is in order of magnitudes smaller than the respiration signal and is usually buried in a noisy signal. In this research, we propose a multivariate signal decomposition for efficiently extracting the heartbeat signal. The results show that the proposed method significantly improves the accuracy of the signal-to-noise ratio of the heartbeat signal compared to the recent advanced methods such as wavelet transform, singular spectral analysis, and multivariate singular spectral analysis. The proposed method also improves the stability of heartbeat monitoring in real-time applications.","PeriodicalId":296346,"journal":{"name":"2023 IEEE Statistical Signal Processing Workshop (SSP)","volume":"19 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121276875","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}

Based on the notion of efficient short-term entropy estimators, we examine the concept of extending information geometry to information topology as a method of characterizing natural sequences. A normalized relative difference entropy method is described, which is required to apply the technique to sub-word models derived from natural sequences. Visualization of information topological spaces is considered, and some aspects are considered for future work.

Unlike existing networks, we consider unpaired medical images as input, and provide a strictly bound generative network that yields a stable cyclic (bidirectional) translation. It consists of two cyclically connected conditional GANs where both generators (32 layers each) are conditioned with concatenation of alternate unpaired patches from input and target images of the same organ. The key idea is to exploit cross-neighborhood contextual feature information to bound translation space and boost generalization. Further, the generators are equipped with adaptive dictionaries which are learned from the cross-contextual patches to reduce possible degradation. Discriminators are 15-layer deep networks which employ minimax function to validate the translated imagery. A combined loss function is formulated with adversarial, non-adversarial, forward-backward cyclic, and identity losses that further minimize variance of the proposed learning machine. Qualitative, quantitative, and ablation analysis show superior results on real CT and MRI datasets.","PeriodicalId":296346,"journal":{"name":"2023 IEEE Statistical Signal Processing Workshop (SSP)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131092237","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}

Robustness issue plays an important role in distributed learning since attacks on agents would strongly affect the convergence performance and even lead the collaboration to an incorrect global solution. In this paper, we consider the attacks as disturbance and propose a joint time-graph filtering to defend against the attacks in distributed learning. The coefficients of joint filtering can be determined based on the coefficients of time-domain and graph-domain filters that are designed separately. If there is no attack in distributed learning, the joint time-graph filtering can also contribute to the convergence performance acceleration. Numerical studies demonstrate that the joint filtering in both time domain and graph domain can defend against attacks with noise and outperforms several existing algorithms.","PeriodicalId":296346,"journal":{"name":"2023 IEEE Statistical Signal Processing Workshop (SSP)","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115936396","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}
