We jointly optimize the transmit precoding (TPC) matrix and the IRS phase shift matrix to maximize the sum secrecy rate subject to the transmit power constraint and the IRS unit modulus constraint. The original problem is a non-convex problem that is very difficult to deal with. We solve this problem by alternating optimization (AO) algorithm. We decompose it into two subproblems, which are solved by successive convex approximation (SCA) and semi-definite relaxation (SDR) methods, and optimize these two subproblems alternately. Finally, simulation results reveal the impact of HIs on confidential communication and verify the effectiveness of our algorithm.","PeriodicalId":199421,"journal":{"name":"2022 14th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127866672","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}

To better address this issue, we present an encoder-decoder network with a lightweight backbone and a lane feature enhancement module in this paper. Specifically, the lightweight backbone built with D-factorized convolutions helps to improve the speed of extracting drivable area features and reduce the number of parameters. The lane feature enhancement is realized by the non-local block at the high-level semantic stage, enhancing the features of the drivable areas such as lane line, direct lane, and alternative lane according to the similarity with the surrounding pixels. By compressing the decoder, the running speed of the proposed model is further improved without losing accuracy. A series of comparative experiments on the BDD100K dataset demonstrated that the proposed model has a better trade-off between speed and accuracy for multilane drivable area detection than the existing state-of-the-art models.","PeriodicalId":199421,"journal":{"name":"2022 14th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115656224","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 signal transmits through multiple paths, where different Doppler frequency offsets (DFOs) are related with distinct angle of departures (AoDs) and hence resulting in fast time-varying of the channel in uplink transmission. To solve this problem, we propose a method for Doppler compensating in the angle domain based on Multi-agent Deep Deterministic Policy Gradient (MADDPG) framework. Specifically, we design a beamforming network using a large-scale uniform linear array (ULA) at both the transmitter and receiver, where different parallel beam branches separate different DFOs, which can be compensated accordingly before transmission starts. The simulation results indicate that our proposed scheme can achieve effective performance in Doppler compensation, and at the same time, it can achieve comparable performance with respect to exhaustive search with lower complexity.","PeriodicalId":199421,"journal":{"name":"2022 14th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114560079","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}

Due to its excessive amount of spatial degrees of freedom, massive multiple-input multiple-output (MIMO) technology can provide reliable services for multiple devices using the same time and frequency resources. In this paper, we consider the transmission design for a massive MIMO-enabled URLLC network. To reduce the pilot overhead, we develop an algorithm to design the precoding matrix that only relies on statistical CSI. Meanwhile, by taking into account the outage probabilities of all devices, the transmit power at the BS is minimized. By using decomposition-based large deviation inequality, the original outage probability constraint is converted into a series of second-order cone (SOC) constraints, which can be efficiently solved. Simulation results demonstrate the low complexity of our proposed algorithm, and also show that the transmit power decreases with the number of antennas.","PeriodicalId":199421,"journal":{"name":"2022 14th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123727425","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}

Our goal is to jointly optimize the output signal-to-interference-plus-noise ratio (SINR) at the DFRC radar receiver and the multi-user interference (MUI) at communication users. To tackle this issue, we propose an optimization method to jointly design the transmit waveform and the receive filter at the DFRC base station and the phase-shift matrix at the RIS, subject to the total DFRC transmit power. Specifically, an alternating optimization-based algorithm is proposed to solve the formulated problem after Dinkelbach's transform, where the transmit waveform and the RIS phase-shift matrix are respectively resolved by two variants of gradient projection method and the receive filter is obtained in light of the minimum variance distortionless response method. Numerical results show that the RIS-aided MIMO DFRC system can not only effectively sense the target at areas with LoS links blocked, but also improve the achievable sum-rate for multi-user communication.","PeriodicalId":199421,"journal":{"name":"2022 14th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129500607","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}

Moreover, we adopt the particle swarm optimization algorithm to obtain the optimal value of the damping factor to balance a trade-off between the error rate performance and decoding complexity.

We consider a small access point (sAP) with limited computation-resources actively offloads its computation tasks toward a group of surrounding fog computing nodes (FCNs) by leveraging the NOMA transmission. Meanwhile, considering that the FCNs might be energy-constrained, the sAP adopts SWIPT to perform the multi-access offloading to the FCNs and transfer energy to them simultaneously, such that the FCNs can harvest sufficient energy to complete their respective task-processing services. To study this problem, we formulate a joint optimization of multi-access offloading decisions, the NOMA-SWIPT transmission duration, the power-splitting factors, and the FCNs' processing-rate allocations, with the objective of minimizing a system-wise cost that covers the overall latency in completing the sAP's workloads as well as the total energy consumption. Despite the strict non-convexity of the joint optimization problem, we propose a layered approach for efficiently solving it. We identify the hidden convexity of the subproblem under the given the sAP's transmit-powers to the FCNs, and further propose an efficient stochastic learning algorithm, which is based on the principle of cross-entropy (CE), to compute the sAP's optimal transmit-powers toward different FCNs in the NOMA-SWIPT transmission.
