The proposed technique employs Deep Learning (DL) models which utilize the, commonly discarded, odd-indexed samples of the received signal in order to enhance the channel estimation. Three DL models with different sets of input features are proposed. The three proposed DL models were trained and then deployed into a UFMC system to evaluate their performance. The performance metric for the training stage is the Normalized Mean Squared Error (NMSE) between the estimated channel and actual channel coefficients. For deployment stage, both NMSE and Bit Error Rate (BER) are chosen as performance metrics. The proposed models are compared versus conventional Least Square (LS) channel estimator. The results show that the proposed DL-models outperform the LS channel estimator for various Signal to Noise Ratio (SNR) even for channel models which are different from the one used for training. The SNR gains of utilizing the proposed models are 5-6dBs and 2-3dBs on average for NMSE and BER, respectively.","PeriodicalId":129532,"journal":{"name":"2023 40th National Radio Science Conference (NRSC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125542911","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}

Various transmit pulsing and postprocessing schemes are typically used for CEUS imaging to extract the nonlinear MB waveform from the echo signal. However, a new software solution called pulse inversion spectral deconvolution (PISD) has been introduced that can separate tissue and MB signal components without the need for a specific pulse selection. The study detailed herein aims to describe a novel three-dimensional (3-D) PISD-based CEUS imaging system and method. US data was collected using a research scanner (Vantage 256, Verasonics Inc) equipped with a 1024-element matrix array transducer (Vermon) and a vascularized phantom (Model ATS 524, Sun Nuclear) linked serially with a flow pump and mixing chamber filled with a MB contrast agent (Definity, Lantheus Medical Imaging) in water solution. 3-D PISD-based CEUS images were produced offline by custom MATLAB software (Math Works Inc), which involved using a pair of Gaussian derivative functional filters applied to backscattered US channel data before envelope detection and volume reconstruction. A contrast-to-noise ratio (CNR) measure was used to quantify contrast enhancement between PISD and standard B-mode CEUS images of the perfused phantom material. Results showed that 3-D PISD-based CEUS imaging provided a 40 dB increase in vessel enhancement compared to B-mode CEUS images. Overall, these preliminary in vitro findings suggest that 3-D CEUS with PISD postprocessing has potential as a valuable addition to the current vascular imaging techniques.","PeriodicalId":129532,"journal":{"name":"2023 40th National Radio Science Conference (NRSC)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124486125","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 study involves comparing the results obtained from the proposed CNN model with those obtained from Random Forest which is a well-known machine learning technique utilized frequently in IDSs.

Two datasets were used, UNSW-NB15 and CSE-CICIDS2018, to demonstrate the efficacy of our proposed model. The proposed CNN model achieved better results than the Random Forest algorithm. A comparison with existing recent IDSs was carried out. The result of this study provides insights and proves the effectiveness of using CNNs for IDSs and helps in identifying the best approach for building efficient and accurate CNN based IDSs with the accuracy of 99.18% using CSE-CICIDS2018 dataset and 99.70% using UNSW-NB15 dataset.","PeriodicalId":129532,"journal":{"name":"2023 40th National Radio Science Conference (NRSC)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123241213","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}

As the world witnesses a huge progress in all fields, radar targets become small in size, and they often have a structure designed according to the stealth topology. As a result, their detection becomes a hard operation. Therefore, there is an insistent need for techniques that increase the system processing gain, to boost the its detection performance. Almost all proposed methods for increasing the radar processing gain require huge physical resources in the radio frequency front-end, or in the digital signal processing hardware implementation. Therefore, these solutions seem to be expensive and sometimes not practical. In this article, we are introducing a technique for increasing the radar system processing gain operating with phase-coded signals, which in turn enhances the system SNR and its detection capability. The proposed approach depends on using $n$ samples per the received signal subpulse, using two coherent pulse intervals for taking decisions. In addition, the required hardware resources for the practical implementation of the suggested method is near to the conventional processing that depends on one sample per subpulse. The method methodological model will be discussed, and the simulation results are presented to ensure the advantage of the proposed technique.","PeriodicalId":129532,"journal":{"name":"2023 40th National Radio Science Conference (NRSC)","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128345931","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}

IoT botnet attacks are the most common. Despite the plethora of detection and prevention systems for cyberattacks, a security mechanism for IoT settings is still required since these devices have certain restrictions that make it difficult to properly implement the detection system. These memory resources are limited to processing, storing, and calculating. An effective defense against cyberattacks is an intrusion detection system (IDS). To develop the rules for IDS_MDL-IoT, we used the contemporary botnet attack dataset. Because IoT devices have limited resources, it is difficult to employ all attack patterns in the initial anomaly dataset in traditional anomaly-based IDS. Therefore, in this study, the tested ML model resulting in NB has proven to be the best classification algorithm to classify the risk of attack with 99.7% accuracy predicting from a time-speed of 3 seconds, and the tested DL model resulting in RNN has proven to be the best classification algorithm to classify the risk of attack with 99% accuracy predicting from a time-speed of 8 seconds.","PeriodicalId":129532,"journal":{"name":"2023 40th National Radio Science Conference (NRSC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123543636","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 technique adopts a joint wireless transmission optimization approach for both the client and the network sides. The amendment in the wireless transmission from the client-side perspective utilized the concurrent load balance over the heterogeneous wireless connections.

In this research, we investigate the generalization between a classical stress inducer, namely, mental arithmetic stressor (MAE), and the stress induced by immersive technologies, particularly virtual reality (VR)-VR-induced stress. On a group of three participants, we acquired EEG recordings following their exposure to the two types of stressors mentioned above. Using multiple machine learning (ML) classifiers, we show that even basic ML models, when trained to differentiate between the MAE stressor and the non-stress state, can generalize well when tested on differentiating between VR-based stress and the non-stress state.
