It has been shown that non-orthogonal multiple access (NOMA) based on power multiplexing could potentially offer a robust performance in the spectrum utilization efficiency. However, when the terminal performs demodulation, the difference in user power superposition and the non-uniformity of user distribution may lead to some severe problems such as intensive excessive power or insufficient signal-to-noise ratio (SNR) under different scenarios, the performance of the communication system is reduced. Therefore, in this paper, a two-stage adaptive weight-adjusting interference cancellation (AWIC) demodulation technology based on symbol level based interference cancellation (SLIC) and code word level interference cancellation (CWIC) has been developed and presented. Moreover, we analyzed the downlink transmission performance of NOMA, innovated the multi-stage adaptive weight-adjusting serial interference cancellation (SIC) demodulation technology, and adjusted the depth of the demodulation algorithm according to the posterior decoding performance feedback. It improves NOMA demodulation performance under a low SNR environment and reduced the complexity under a high SNR environment. According to the computer simulations, under the average bit error rate (BER) of $3times 10^{-2}$, the improved NOMA interference cancellation approach proposed in this paper has a 5.09 dB performance improvement compared to SLIC and 9.8 dB compared to CWIC.","PeriodicalId":415094,"journal":{"name":"2021 International Conference on Signal Processing and Machine Learning (CONF-SPML)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114411658","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 fifth-generation(5G) era has arrived in an all-round way, and 5G technology has achieved a wide range of applications and brought great convenience to our life. With the all-round development of 5G technology, we begin to look forward to the future sixth-generation(6G) technology. In many conferences and reports, we have put the 6G technology research on the agenda. As an effective way to control the wireless environment channel manually, Intelligent Reflecting Surface(IRS)1 has become one of the 6G developable technologies and is getting more and more attention. IRS assisted wireless channel and the change of channel model are important research contents in the future wireless communication. Channel model is divided into large-scale model and small-scale model, among which the research of large-scale model is the most important one in the future technical research. The model of IRS Assisted Wireless Channel is still relatively basic in the current research, so this paper aims to further explore and research. In this paper, based on the model of path loss in free space, we analyze the path model of IRS assisted wireless communication transmission. We divide the path loss model into two scenarios: near field and far field. At the end of the article, we use matlab to simulate the theoretical model numerically, and plot the change of path loss results with different distances. We find that the simulation results are basically consistent with the theoretical model.","PeriodicalId":415094,"journal":{"name":"2021 International Conference on Signal Processing and Machine Learning (CONF-SPML)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130196003","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, large online platforms like Amazon allows all users to leave reviews composed of a rating and a comment to any product, whether the purchased it or not. Reviews that are immediately visible influence the purchase decisions of potential customers, therefore the platforms need to sort the reviews so that the first few reflect the product’s quality accurately. However, current algorithms are still not yet mature enough for the task. In order to determine the credibility and reliability of online product reviews, we summarize the factors typically considered in review sorting studies into four categories: product-specific factors, general attitude factors, reviewer-specific factors, and time factors. We then examine the contents and implications of each category. Future designers of algorithms can use the factors to their advantages.","PeriodicalId":415094,"journal":{"name":"2021 International Conference on Signal Processing and Machine Learning (CONF-SPML)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129300443","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}

Any possible abnormal migration will cause price change. Thus, the migration could be tackled by comparing the current price trend with the data in past 10 years. COVID-19 is a strong effect which could cause migration. In order to observe the possible migration under this situation, wo high-population states were chosen as examples – California and New York, to compare with two low-population states – Nevada and Ohio. Three machine learning techniques have been used (Random Forest, XGboost, and Ridge and Lasso regression) to forecast housing price in U.S.: the difference between the real price and forecast price trend will show the amount of real estate transactions affect by the pandemic. The observed data was compared with the predicted results after COVID-19.

It is found that there are some problems in the current clinical use of DBS (which is always called conventional deep brain stimulation (cDBS), such as the adjustment of parameters requires doctors to adjust parameters by experience. In the improvement process of DBS, adaptive deep brain stimulation (aDBS) has been widely studied because of its ability to better adjust the parameters.
