The majority of Multi-agent Reinforcement Learning (MARL) methods for solving Adaptive Traffic Signal Control (ATSC) problems are dedicated to maximizing the throughput while ignoring fairness， resulting in a bad situation where some vehicles keep waiting. For this reason， this paper models the ATSC problem as a Partially Observable Markov Game (POMG)， in which a value function that combines throughput and fairness is elaborated. On this basis， we propose a new cooperative MARL method FA-MAPPO， i.e.， fairness-aware multi-agent proximity policy optimization， which is based on the cooperative MARL algorithm MAPPO. In addition， FA-MAPPO uses graph attention neural networks to efficiently extract state representations from traffic data acquired through visual perception in multi-intersection scenarios. Experimental results in Jinan and synthetic scenarios confirm that FA-MAPPO improves fairness while guaranteeing passage efficiency compared to the SOTA methods.

For free-space optical communication atmospheric turbulence has a large impact on signal modulation， the convolution-profile stellar data image conversion algorithm proposed in this paper performs data conversion on the received constellation maps so that they retain more original signal feature images. A classification network based on the channel attention mechanism is proposed to classify the modulated signals by extracting the feature information in the image through the residual structure， and the attention mechanism assigns different weights of the channel features. Under the same data conversion algorithm， the proposed classification network achieves the highest recognition accuracy of 96.286%.
