Moreover, the RIS explicitly embeds its information bits in the discrete phase shifts of reflecting elements, which are selected from the reflection phase modulation (RPM) constellation. Further, access point (AP) exploits the pulse amplitude modulation (PAM) constellation to convey its information bits. Both RIS and AP independently transmit their data to the receiver using RPM and PAM symbols. In addition, joint decoding of RPM and PAM constellations symbols is performed using a maximum likelihood (ML)-detector, and a tight upper bound of the average bit error rate (ABER) is presented. A unified analytical framework of the average pairwise error probability over double Rayleigh fading channels is derived, which is followed by the ABER expression. Furthermore, it is noticed from the numerical results that the proposed scheme attains high data rates with remarkably lower error rates in very low SNR regime.","PeriodicalId":246982,"journal":{"name":"2022 IEEE International Conference on Signal Processing and Communications (SPCOM)","volume":"50 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116119871","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}

It is required to preserve every user’s privacy and security of information on the Internet. While data security is primarily taken care of by the TLS protocol and broader adaptation of HTTPS, FTPS, and SMPTS protocol, some fields of TLS expose the type of activity a user is performing, thus violating user privacy. One such protocol information is Server Name Indication (SNI) in the TLS ClinetHello message that goes in plaintext. Anyone intercepting the message thus identifies the service host type. We present a method named Extended TLS (ETLS) to mask the server host identity by encrypting the SNI without requiring any change in the existing protocols. In ETLS, a connection is established over two handshakes - the first handshake establishes a secure channel without sharing SNI information, and the second handshake shares the encrypted SNI. ETLS requires no modification in the already proven TLS encryption mechanism and retains all security benefits of the existing secure channel establishment. We demonstrate the feasibility of ETLS over live Internet with scripts that implement our methodology. Using a customized client-server and a commercial traffic shaper, we also demonstrated that the host identity is not exposed under ETLS, thus demonstrating its privacy-preserving property.","PeriodicalId":246982,"journal":{"name":"2022 IEEE International Conference on Signal Processing and Communications (SPCOM)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126725285","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}

Finite Rate of Innovation (FRI) approaches allow for sampling at sub-Nyquist rates. Empirical Mode Decomposition, which recursively decomposes a signal into different modes of unknown spectral bands, has performance limitations such as sensitivity to noise and sampling rates. These limitations are partially addressed by several variant algorithms; one of them is Variational Mode Decomposition (VMD), an entirely non-recursive model to extract the modes concurrently. In this paper, we propose an approach using FRI-based technique to estimate the delay of the target, and a VMD-based approach for Doppler and micro-Doppler parameter estimation. A novel mathematical analysis is proposed to identify the initialization parameters for faster convergence of the VMD algorithm. Further, we provide simulation results to show that the proposed approach is capable of estimating the parameters of multiple targets even in the presence of noise.","PeriodicalId":246982,"journal":{"name":"2022 IEEE International Conference on Signal Processing and Communications (SPCOM)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133256909","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}

This sensitivity is a limiting factor in the performance of the quadrature amplitude modulated (QAM) SM. We propose three novel MIMO-SM constellation designs to mitigate the performance limitation: (i) a hybrid PSK-QAM MIMO-SM that leverages the constant modulus phase shift keying (PSK) in conjunction with the QAM to minimize the sum of the antenna errors and the APM symbol errors. This is achieved by increasing the number of transmit antennas, which need not be an integer power of two; (ii) MIMO-SM with a novel APM QAM constellation, with optimized radius of the inner constellation ring; and (iii) a MIMO-SM that transmits the QAM symbols from the inner ring on different orthogonal resources (e.g., subcarriers) to reduce their impact on the antenna errors. The simulation results demonstrate the performance benefit of the proposed approaches compared to the conventional SM.","PeriodicalId":246982,"journal":{"name":"2022 IEEE International Conference on Signal Processing and Communications (SPCOM)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133554370","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}

Hence, adversarial samples can mislead already trained deep networks. The process of generating adversarial examples can assist us in investigating the robustness of different models. Many developed adversarial attacks often fail under challenging black-box settings. Hence, it is required to improve transferability of adversarial attacks to an unknown model. In this aspect, we propose to increase the rate of transferability by inducing linearity in a few intermediate layers of architecture. The proposed design does not disturb the original architecture much. The design focuses on significance of intermediate layers in generating feature maps suitable for a task. By analyzing the intermediate feature maps of architecture, a particular layer can be more perturbed to improve the transferability. The performance is further enhanced by considering diverse input patterns. Experimental results demonstrate the success in increasing the transferability of our proposition.","PeriodicalId":246982,"journal":{"name":"2022 IEEE International Conference on Signal Processing and Communications (SPCOM)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124562299","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 analysis of EGG signal has many applications in the literature such as speech-to-text synthesis, voice disorder analysis, emotion recognition, speaker verification, etc. Therefore, the EGG device is essential to record the vocal folds activity. Alternatively, a new method is proposed in this work to synthesize the EGG waveform from speech signal using a context aggregation convolutional neural network. The synthesis network is trained by accounting the deep feature losses obtained by comparing it with another network called the EGG classification network. The synthesized EGG signal needs to be characterized. During the voiced speech production, the instants at which the vocal folds attain complete closure are called glottal closure instants (GCIs). Likewise, the opening instants are called glottal opening instants (GOIs). Such instants are reliably measured using the EGG signal. The performance of the proposed method is compared with other state-of-the-art techniques. The CMU-Arctic database has a parallel corpus of speech and EGG signal recorded simultaneously. This database is used for training the synthesis network and for comparison purposes. It is found that the performance of extracting glottal instants from synthesized EGG signals is comparable to other methods.","PeriodicalId":246982,"journal":{"name":"2022 IEEE International Conference on Signal Processing and Communications (SPCOM)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125330721","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}
