Previous methods only rely on GAN-based model with the sun position to reconstruct the street view. Lacking in related dataset, we propose an evaluation method to make sure of the effectiveness. Our model applies a 2D-to-3D lifting method, casts the 3D object with sun estimation, and finally merges the shadow with a predicted sun brightness. Limited with lifting objects, our model casts more precise shadows than GAN-based model. Tuning with the brightness, the cast shadow will be in consistence with the whole street view. Then in our evaluation, we demonstrate better performance over the state-of-the-art models by 0.009 in LPIPS. Therefore, casting with a 3D human object is a feasible solution for shadow generation in the future.","PeriodicalId":375211,"journal":{"name":"2023 VTS Asia Pacific Wireless Communications Symposium (APWCS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130690939","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}

Then, it is integrated with a multi-agent proximal policy optimization (MAPPO) algorithm to efficiently perform the PA task. Our proposed MADRL-based algorithm with the reduced action mapper is able to find the sub-optimal solution according to the current environmental condition.

A novel controlled counter is designed and used to implement the ECP oracle to check if every element is covered by a set exactly once. If so, a feasible solution is found. The phase of the qubit state representing a feasible solution is flipped by calling the oracle, and the state’s amplitude is amplified through the diffusion operator o($sqrt{2^{n}}$) times, where n is the number of sets given in the ECP. Thanks to Grover’s algorithm, the proposed quantum circuit achieves quadratic speedup compared with the classical algorithm that needs to call the oracle O($2^{n}$) times. To validate our approach, we execute the proposed quantum circuit using the IBM Quantum Lab service.","PeriodicalId":375211,"journal":{"name":"2023 VTS Asia Pacific Wireless Communications Symposium (APWCS)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117055809","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 show that when there is a CFO, coherent combining (CC) of multiple correlations achieves a lower PRACH MDP than using power domain combining (PC) in the low average received signal-to-noise ratio (SNR) region when a large number of cyclic shift (CS) resources are used with high priority. Conversely, we show that the PC achieves a lower PRACH MDP due to the robustness to the CFO in the high average received SNR region. We also show that the required average received SNR at the target PRACH MDP using the CC is reduced by approximately 2.0 dB compared to using the PC when the maximum number of available CS resources is used. Finally, we show that the required average received SNR satisfying the PRACH MDP of $10^{-2}$ is increased by approximately 4.0 dB compared to that at the MDP of $10^{-1}$ when using the maximum number of available CS resources.","PeriodicalId":375211,"journal":{"name":"2023 VTS Asia Pacific Wireless Communications Symposium (APWCS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124218175","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}
