Space time block coding (STBC) is a popular technique to improve diversity gain of conventional OFDM systems. Vector OFDM (VOFDM) is a transmission technology that exploits signal space dimension to reduce the effect of spectral nulls on OFDM subcarriers. Space time block coded vector OFDM (STBC VOFDM) tries to extract advantages of both these techniques, thereby improving the reliability of the communication system. This paper illustrates the characteristics of STBC VOFDM systems with maximum likelihood (ML) detection in an i.i.d (independent and identically distributed) multipath complex Rayleigh channel with D channel taps. The expression for diversity gain in STBC VOFDM for most vector blocks is derived as 2{min(M, D)}, where M denotes the number of elements in each vector block and D denotes the number of channel taps. It can be observed that the diversity order in STBC VOFDM has improved by a factor of 2 when compared with VOFDM.
空时分组编码(STBC)是提高传统OFDM系统分集增益的一种常用技术。矢量OFDM (VOFDM)是一种利用信号空间维度来减小频谱零值对OFDM子载波影响的传输技术。空时分组编码矢量OFDM (STBC VOFDM)试图提取这两种技术的优点,从而提高通信系统的可靠性。本文研究了具有独立同分布的多径复杂瑞利信道中具有最大似然检测的STBC VOFDM系统的特性。STBC VOFDM中大多数矢量块的分集增益表达式为2{min(M, D)},其中M表示每个矢量块中的元素数,D表示通道分接数。可以看出,STBC VOFDM的分集顺序比VOFDM提高了2倍。

Zoo is a place where animals are cared and looked after by a team of officials. It will also provide entertainment to tourists and the animal lovers to study animal behavior. It is used for learning purposes as well as for tourist revenue. It serves and takes care of many wild animals with the help of zoo administrators. The work of those zoo administrators is very difficult as they are dealing with wild animals in person. In this paper, we proposed an architecture to ease the animal administrator’s daily job by effectively collaborating the Internet of Things (Iot) and Artificial Intelligence (AI). Here we propose a novel and intelligent method for the health prediction of animals by a supervised machine learning algorithm. In addition to that, our architecture involves automatic feeding, cage temperature control, health monitoring of animals, real-time monitoring, and identification of virus infected animals. That helps to make the zoo expenses low. Moreover, in this era of the pandemic, the virus infected animals need to be separated from other animals as well as from the administrators to avoid spreading of the diseases. We also proposed an effective method by using RFID tag to identify virus infected animal and break the chain to prevent the spreading. So, our aim is to uplift the motto one world one health.
动物园是由一组工作人员照顾和照顾动物的地方。它还将为游客和动物爱好者提供研究动物行为的娱乐。它既用于学习目的,也用于旅游收入。在动物园管理员的帮助下,它为许多野生动物提供服务和照顾。那些动物园管理员的工作是非常困难的,因为他们要亲自与野生动物打交道。在本文中,我们提出了一种架构,通过有效地协作物联网(Iot)和人工智能(AI)来简化动物管理员的日常工作。本文提出了一种基于监督式机器学习算法的动物健康预测新方法。除此之外,我们的架构还涉及到自动喂食、笼子温度控制、动物健康监测、实时监测、病毒感染动物的识别。这有助于降低动物园的开支。此外,在这个大流行的时代,感染病毒的动物需要与其他动物以及管理人员分开,以避免疾病的传播。我们还提出了一种有效的方法,利用RFID标签识别病毒感染的动物,打破病毒链,防止病毒传播。因此,我们的目标是提升“同一个世界,同一个健康”的座右铭。

This paper focuses on developing a prediction model to predict heart stroke using the parameters, namely, age, hypertension, previous heart disease status, average body glucose level, BMI, and smoking status. The prediction model is developed using a support vector machine (SVM) algorithm. Further, the SVM algorithm with various decision boundaries like linear, quadratic, and cubic are also produced. The performance prediction results show that the linear and quadratic SVM has performed better in predicting the heart stoke with greater accuracy values. This is true for both the male and female databases during training and testing.

This paper focuses on developing a weather prediction model to predict temperature and humidity. Further, a classification model is also extended to predict the weather condition using the expected model’s output. The proposed hybrid model can predict the temperature and humidity and forecast future weather conditions. The prediction and classification models are created using neural networks and k-nearest neighbors, respectively. The prediction model’s results have shown the best ability for both the output variables (temperature and humidity) with R2 values close to one and MSE values close to zero. Further, the classification model’s results also showed better execution in classifying the weather conditions with the highest accuracy values.

The zero memory set partitioned embedded block (ZM-SPECK) technique is an embedded and memory efficient image compression algorithm. However, it is computationally complex due to the repetitive significance checking of sets and coefficients in each and every bit plane. To overcome this limitation, it is proposed to parallelize the algorithm over smaller blocks to reduce the overall encoding and decoding times of ZM-SPECK algorithm. The proposed approach called block based parallel ZM-SPECK (BPZM-SPECK) decomposes the wavelet transformed image into independent nonoverlapping spatial blocks utilizing the unique child-parent relationships in spatial orientation trees (in wavelet domain) and concurrently encodes every single bits in each bit plane of a block. The experimental results show significant improvement in computation time over the existing ZM-SPECK algorithm.
零存储集分割嵌入块(ZM-SPECK)技术是一种嵌入式和内存高效的图像压缩算法。然而,由于在每个位平面上对集合和系数进行重复的显著性检查,计算起来很复杂。为了克服这一限制,提出了在更小的块上并行化算法,以减少ZM-SPECK算法的整体编码和解码时间。提出了一种基于块的并行ZM-SPECK (BPZM-SPECK)方法,该方法利用空间方向树(小波域)中独特的父子关系,将小波变换后的图像分解为独立的非重叠空间块,并对块的每个位平面上的每个位并行编码。实验结果表明,与现有的ZM-SPECK算法相比,该算法在计算时间上有显著提高。

VoWiFi Cell Capacity Estimation Using Fifth Generation WLAN Standard 基于第五代无线局域网标准的VoWiFi小区容量估算
Pub Date : 2021-07-01 DOI: 10.1109/ICSCC51209.2021.9528161

The growth of Wireless Local Area Network (WLAN) deployment specifically over the existing infrastructure is increasing tremendously. Such an infrastructure-based WLAN, commonly known as Wireless Fidelity (WiFi) network, needs to support voice service since in general it contributes a significant portion of the traffic supporting personal communication. In this context, Voice over Internet Protocol (VoIP) over WiFi or Voice over WiFi (VoWiFi) is one amongst the very prominent solutions. To ensure Quality of Service (QoS) for VoWiFi calls, it is essential to develop an adequate call admission control (CAC) policy. Such policy requires VoWiFi cell capacity. In this paper, we have derived analytical models to find capacity of the IEEE 802.11ac standard Access Point (AP) providing VoWiFi service. To analyze WLAN AP capacity for VoWiFi service, we have used DCF Inter-frame Spacing (DIFS) for sensing channel status before sending data from one station to another and Short Inter-frame Spacing (SIFS) is used for acknowledgement, Request To Send (RTS) and Clear To Send (CTS) frames. Further, we have used the compressed RTP (cRTP) protocol to optimize VoIP call bandwidth. Using our proposed analytical model, we have estimated VoWiFi cell capacity using different voice codecs like G.729 and G.723.1.
无线局域网(WLAN)部署特别是在现有基础设施上的增长正在急剧增加。这种基于基础设施的WLAN,通常被称为无线保真(WiFi)网络,需要支持语音服务,因为它通常在支持个人通信的流量中占很大一部分。在这种情况下,基于WiFi的互联网协议语音(VoIP)或基于WiFi的语音(VoWiFi)是非常突出的解决方案之一。为了保证VoWiFi呼叫的服务质量(QoS),必须制定适当的呼叫接纳控制(CAC)策略。这样的策略需要VoWiFi小区容量。本文推导了IEEE 802.11ac标准接入点(AP)提供VoWiFi服务的容量分析模型。为了分析VoWiFi服务的WLAN AP容量,我们使用DCF帧间间隔(DIFS)在将数据从一个站点发送到另一个站点之前感知信道状态,并使用短帧间间隔(SIFS)用于确认,请求发送(RTS)和清除发送(CTS)帧。此外,我们还使用压缩RTP (cRTP)协议来优化VoIP呼叫带宽。使用我们提出的分析模型,我们使用不同的语音编解码器(如G.729和G.723.1)估计了VoWiFi蜂窝容量。

A worldwide pandemic, COVID-19 has been caused by a newly discovered strain of coronavirus SARS-Cov-2. Its common symptoms are high fever, coughing, and shortness of breath. With the rising number of COVID-19 cases, manual detection of infectious individuals at public spaces is a hectic task. Artificial Intelligence (AI) based detection systems can be deployed at public places like airports, railway stations, etc. for continuous monitoring of potential infectious individuals and screening based on common symptoms exhibited. In this paper, a new algorithm is developed for detecting repetitive coughing action which is the main symptom in COVID-19 cases, and thus detecting people with COVID-19 based on it. The performance of the proposed system is tested on an existing sneeze-cough dataset and also on a real-time dataset. The evaluation shows that the proposed method has superior performance over the state-of-the-art methods.

Artificial Intelligence (AI) based detection systems can be deployed at public places like airports, railway stations, etc. for continuous monitoring of potential infectious individuals and screening based on common symptoms exhibited. In this paper, a new algorithm is developed for detecting repetitive coughing action which is the main symptom in COVID-19 cases, and thus detecting people with COVID-19 based on it. The performance of the proposed system is tested on an existing sneeze-cough dataset and also on a real-time dataset. The evaluation shows that the proposed method has superior performance over the state-of-the-art methods.","PeriodicalId":382982,"journal":{"name":"2021 8th International Conference on Smart Computing and Communications (ICSCC)","volume":" 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120826757","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}
