In order to reduce the variance of the spectral component of background noise, Welch method is derived. However, Welch method only considers the non coherent information so that it will lead to the loss of gain. The existing coherent average detection method which is based on phase compensation can enhance the processing gain of line spectrum signals. In this paper, an improved coherent average power spectrum detection technique is proposed by combining polynomial fitting technique with coherent average detection method. The simulation results show that this method can reduce the fluctuation of background noise further, and its performance is better than the coherent average power spectrum method.","PeriodicalId":170939,"journal":{"name":"2023 6th International Conference on Communication Engineering and Technology (ICCET)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114128968","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}

In this end, we propose a multi-scale convolution and ghost attention head. The former is inserted into the encoder, which increases the receptive field of the network and makes the network more effective to obtain context information. At the same time, a Ghost Attention Head is designed in the process of decoding, which adopts cheap operation and separable attention to guide the network, so as to solve the problems such as computational cost and ignoring spatial information. Experimental results on CamVid show that the mIoU of the proposed module reaches 71.32%, which is 9.7% higher than that of the traditional semantic segmentation network FCN. Ablation experiments were also carried out to further verify the effectiveness of the added module.","PeriodicalId":170939,"journal":{"name":"2023 6th International Conference on Communication Engineering and Technology (ICCET)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128651959","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 tensor theory is used to model multidimensional situation information, and a new definition of situation sensing is provided for power emergency communications.

In this paper, a quantile regression method based on manifold learning is proposed for the short-term power load probability density forecasting. Considering the good performance, the local linear embedding (LLE) method (i.e., one excellent manifold learning method) is used to reduce the dimension of the data, which can extract the underlying factors of power load to improve the forecasting accuracy and significantly reduce the complexity. Then we use a BI-LSTM network to better analyze the time correlation of the low-dimensional data, so as to better forecast the power load under different quantiles. Considering the good performance of the Gaussian kernel function, we use the Gaussian kernel smoothing method to derive the power load probability density. Simulation results on actual power load data validate that the proposed model can provide a better performance than other quantile regression methods.","PeriodicalId":170939,"journal":{"name":"2023 6th International Conference on Communication Engineering and Technology (ICCET)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115286103","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}

We analyze the rate performance of a cooperative transmission system based on ZF linear processing. At the same time, relevant factors affecting the rate are discussed, including the number of massive transmitting and receiving antennas array set by the relay station, transmitting power of the relay station and loop interference. The system performance will be affected by the relay station loop interference, resulting in the system rate performance decline. Generally, a large scale transmitting and receiving antenna can be set up on the relay station to avoid the continuous influence of loop interference on system performance. The total achievable rate of the system depends on the minimum achievable rate of the two links from the source station to the receiving end of the relay station, and the transmitting end of the relay station to the destination. We adjusted transmission power which is set by the relay station to make the sum achievable rate increase to a certain extent, that is to say, the minimum achievable rate of the above two links increases. Experimental data show that better achievable speed can be obtained by adjusting the transmission power of the relay end when the signal to noise ratio(SNR) is high. The achievable rate can be improved continuously in the whole channel state signal-to-noise ratio condition by setting different power of relay station simultaneously.","PeriodicalId":170939,"journal":{"name":"2023 6th International Conference on Communication Engineering and Technology (ICCET)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130900011","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}

Usually, straight 90-degree edges are used for classroom corners, but rounded edges for walls and furniture are more comfortable and help to ensure students safety. Therefore, this study examines how a rounded-edge classroom design for walls and furniture affects additive babble and environmental noise level conditions in primary school classrooms for intellectually disabled students. The study compares the two classroom designs (rounded and right-angle corners) covering the same area with different variable factors to improve students’ performance. The computer software program ODEON and the MATLAB programming language were primarily used to investigate the two models. These models were used to predict five design scenarios’ impact to assess acoustic behavior with and without furniture on intellectually disabled students learning. The findings reveal that the proposed model with rounded corner walls and furniture and a high and sloped ceiling performs better than the regular classroom model. The study also confirms that a better study environment can be created for intellectually disabled students to study alongside regular students.","PeriodicalId":170939,"journal":{"name":"2023 6th International Conference on Communication Engineering and Technology (ICCET)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121674808","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}

However, multi-hop communication will lead to uneven distribution of network energy consumption and premature death of nodes. To prolong the network lifetime of digital oilfields, we extended the narrowband internet of things (NB-IoT) module on some WSN nodes deployed on site to form heterogeneous nodes. Through the heterogeneity of NB-IoT and WSN, the nodes could transmit as little data as possible from other nodes, fundamentally reducing the node energy consumption. Furthermore, an optimization method was proposed that could simultaneously optimize the network lifetime and node expansion cost. The experimental results revealed that the proposed algorithm could greatly prolong the network lifetime while only introducing a small number of nodes.","PeriodicalId":170939,"journal":{"name":"2023 6th International Conference on Communication Engineering and Technology (ICCET)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122750907","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 antenna adopts the cross-dipole structure, containing two radiation units orthogonal to each other to achieve ± 45° linear polarizations. For each dipole unit, the parasitic elements placed perpendicular and parallel to it introduce radiation nulls at lower and higher frequencies, respectively. Through a pair of slits etched on each parasitic element, the roll-off rate at the upper passband edge is further optimized. In addition, the two radiation nulls can be controlled independently by adjusting the inner and outer lengths of the Uslot on the coupling path.
