Abstract

The satellite transmission industry is diverse, catering not only to data services but also requiring the transmission of control signals. These two aspects have different performance indicators. Additionally, this paper takes into account non-ideal factors such as limited transmission rates, channel errors, and actual spectral effects, which are the difficulties that satellite communication systems need to overcome. Based on these considerations, a multi-objective optimization problem is proposed to strike a balance between power and performance for power-sensitive satellite systems. However, the original problem is challenging to solve directly. Hence, we have designed a multi-step optimization algorithm framework. This framework solves the intermediate problem indirectly by addressing the easier problem. Subsequently, it indirectly solves the original problem by resolving the intermediate problem. The effectiveness of our algorithm design is demonstrated through experimental simulations.

基于卫星系统实际频谱效率的鲁棒多播波束成形优化

卫星传输行业是多样化的，不仅满足数据服务，而且要求传输控制信号。这两个方面有不同的性能指标。此外，本文还考虑了有限传输速率、信道误差和实际频谱效应等非理想因素，这些都是卫星通信系统需要克服的困难。在此基础上，提出了一种多目标优化问题，以实现功率敏感型卫星系统功率与性能的平衡。然而，最初的问题很难直接解决。因此，我们设计了一个多步优化算法框架。这个框架通过解决更容易的问题间接地解决了中间问题。随后，通过解决中间问题，间接解决了原问题。通过实验仿真验证了算法设计的有效性。

期刊介绍： The scope of the Transactions is threefold (which was approved by the IEEE Periodicals Committee in 1967) and is published on the journal website as follows: Communications: The use of mobile radio on land, sea, and air, including cellular radio, two-way radio, and one-way radio, with applications to dispatch and control vehicles, mobile radiotelephone, radio paging, and status monitoring and reporting. Related areas include spectrum usage, component radio equipment such as cavities and antennas, compute control for radio systems, digital modulation and transmission techniques, mobile radio circuit design, radio propagation for vehicular communications, effects of ignition noise and radio frequency interference, and consideration of the vehicle as part of the radio operating environment. Transportation Systems: The use of electronic technology for the control of ground transportation systems including, but not limited to, traffic aid systems; traffic control systems; automatic vehicle identification, location, and monitoring systems; automated transport systems, with single and multiple vehicle control; and moving walkways or people-movers. Vehicular Electronics: The use of electronic or electrical components and systems for control, propulsion, or auxiliary functions, including but not limited to, electronic controls for engineer, drive train, convenience, safety, and other vehicle systems; sensors, actuators, and microprocessors for onboard use; electronic fuel control systems; vehicle electrical components and systems collision avoidance systems; electromagnetic compatibility in the vehicle environment; and electric vehicles and controls.
