Establishment and performance analysis of RIS-assisted coded relay cooperation system based on LDPC product codes by Shunwai ZHANG, Jin WANG

“…To pursue the ultra-reliable information transmission, the system which combined the reconfigurable intelligent surface (RIS) technology and coded relay cooperation technology was investigated.The RIS-assisted coded relay cooperation system model based on low density parity check (LDPC) product codes was established.Based on LDPC product codes, the information matrix was row-encoded by the source node and column-encoded by the relay node, respectively.An efficient joint iterative decoding algorithm was proposed.The two received signals at the destination were row-decoded and column-decoded iteratively to update the logarithmic likelihood ratios of information bits, and then the decoding decision was made.The closed-form solutions of the outage probability and the channel capacity with finite codelength were theoretically derived.Theoretical analysis and simulation results show that the proposed system obviously outperforms the traditional coded relay cooperation.The more number of RIS elements, the more significant advantage can be obtained.Simulation results also demonstrate that the channel capacity with finite codelength approaches the ideal channel capacity with the codelength of LDPC product codes increasing.…”

Broad spectrum micronutrients: a potential key player to address emotional dysregulation by Amelia Villagomez, Michelle Cross, Noshene Ranjbar

“…Adequate nutritional intake is necessary for optimal mental health and is thus an essential component of any psychiatric treatment plan; this is especially true as many patients have a diet high in ultra-processed foods. However, due to a variety of factors such as individual biological and behavioral contributors, modern farming practices, and climate change, implementing a healthy diet alone may not be sufficient to satisfy nutritional requirements. …”

Performance analysis of 60 GHz pulse multiuser communication system based on cross-layer strategy by Xuehua LI, Chen SHEN, Yuanyuan YAO

“…Due to the advantages of license-free,strong directionality,high system capacity,and high transmission rate of Gbit/s,60 GHz band is listed as one of the candidate bands for new radios (new radio).In 5G ultra-dense networking scenario,the randomness of node switching caused by the decrease of the distance between network nodes may cause severe multiple access interference and resource mismatch problems.In this regard,based on the concept of cross-layer collaborative design,a resource scheduling strategy based on fairness was proposed.The multiple access performance of the strategy was simulated in a 60 GHz pulsed wireless communication system based on TH-PAM (time hopping pulse amplitude modulation).Simulation results show that compared with the system with pure physical layer optimization algorithm,the multiple access system which adopts this strategy shows stronger fairness and lower system error rate,but it needs increase the transmission power to meet the requirements of the coverage of the equivalent communication system.That is,there is a certain trade-off between the energy and fairness of the system,which can be used to guide the structure and deployment of the actual communication system.…”

Research on the edge-end collaboration framework for deterministic network by Guangmin SONG, Qunqing WANG, Zhanbing HUANG, Xun SHI, Gaojian HAN

“…5G vertical industries such as industrial automatic control have strict requirements on network transmission delay and reliability.It was focused on the AGV collaborative carrying scenarios, in which the key quality indicator (KQI) of the AGV collaboration and the requirements for network jitter were analyzed.Existing 5G ultra-low-latency technologies, such as the pre-scheduling mechanism, reduce transmission scheduling latency by reserving a large number of time-frequency resources, which heavily decreases spectrum efficiency.In addition, wireless channel quality factors such as weak coverage and interference, often cause large jitter, making it difficult to meet the service reliability requirements.In order to deal with these challenges, a deterministic edge-end cooperation framework design to guarantee end-to-end latency was proposed.Based on service flow characteristics, resource reservation was utilized to reduce scheduling latency.Moreover, the proposed framework could enhance data transmissions when poor status of channels was sensed.The experimental results show that the edge-end collaboration framework design can effectively increase the delay reliability, reduce the large jitter, and improve the KQI of AGV collaboration.…”
