The upcoming 6G systems must support ubiquitous & massive data services over high-mobility channels (e.g., moving speed at 500 km/h or higher) for various applications such as Satellite IoT and massive V2X access. This motivates us to study the integration of affine frequency division multiplexing (AFDM)-empowered sparse code multiple access (SCMA) system, referred to as AFDM-SCMA, by fully exploiting the complementary strengths of AFDM and SCMA in high-mobility communications and massive machine-type communications, respectively. We propose a novel iterative detection and decoding scheme with linear minimum mean square error (LMMSE) estimator based on orthogonal approximate message passing (OAMP) principles. We show that the proposed receiver can significantly enhance the error rate performance while reducing the detection complexity.

In this talk, we explore innovative strategies to enhance language models

低空经济是指依托于低空空域，以各种有人驾驶和无人驾驶航空器飞行活动为牵引，辐射带动相关领域融合发展的综合性经济形态，广泛体现于各类产业形态，正在逐步构筑智慧城市生产生活新模式、新业态。与此同时，低空无人机“黑飞”扰航、失控伤人、偷拍侵权等问题严重威胁航空安全、公共安全和国家安全，安全风险不容忽视。因此，通过顶层设计，突破无人机智能交通关键技术瓶颈，是低空无人机 “飞起来”“管得住”“热起来”的重要前提。一是，研究基于物理信息融合空间空域精细化管理方法，构建“数字底座”，解决“无路飞”难题。二是，研究空天地一体化态势感知技术，建立“数字链路”，解决“看不见”难题。三是，研究基于轨迹预测改进算法的航线动态规划，建立“智慧天路”，解决“管不住”难题。
