NOMA is a power domain access technique, which ensures better spectrum efficiency and system capacity. However, the representation of NOMA is challenging because of inter-user interference and the complexity of successive interference cancellation (SIC) in the receiver. We suggest a low-complexity power allocation (PA) and user pairing (UP) scheme using a model-free technique that depends on the real-time input and output calculations, data-driven (DD), where the near-optimal solution has been found. So, data-driven can be utilized as an optimization tool for finding a near-optimum solution of the original NP-hard problem of joint PA and UP. Analytical and simulation results referred that the proposed algorithm can enhance spectrum efficiency compared with the existing algorithms.","PeriodicalId":354908,"journal":{"name":"2021 9th International Japan-Africa Conference on Electronics, Communications, and Computations (JAC-ECC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125105038","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 shown that the surface temperature reaches about 3000 K within a few tens of nanoseconds, which reasonably agrees with thermal simulation.

Capsule Networks handle patterns as vectors preserving spatial information of the patterns along with their pose but at the cost of having slow processing and high complexity. Wide Fast Embedded Capsule Networks were introduced as the faster and simpler version of Capsule Networks. However, they could not handle complex datasets like Labeled Faces in the Wild (LFW). That is the reason Wide Fast Embedded Capsule Networks are proposed in this paper to handle intermediate complex datasets like LFW boosting the speed boost, reducing complexity and preserving accuracy.

MIMO systems require high resolution Analog-to- Digital Converters (ADCs) in the Base Stations (BS) to reduce quantization noise. However, using high resolution ADCs causes higher power consumption at the BS and the hardware costs increase. Reducing the resolution of the ADCs at the BS causes severe non-linearity errors due to additional quantization noise. In other words, MIMO systems cannot achieve high performance without highly linear and low resolution ADCs. In this paper, a 3-bit highly linear Time- based ADC (T-ADC) is presented. The proposed circuit exhibits high linearity, simple design and low power which make it the best solution for the problems that limit the performance of the MIMO systems. The proposed ADC exhibits a linearity error of 0.56 % with a dynamic range equals to 800 mV and at small power consumption of 2.2 mW. The supply voltage used equals to 1.2 V using industrial 65 nm TSMC CMOS technology.
