Special Issue Information

Dear Colleagues,

Satellite communication systems have advantages such as wide coverage and large transmission capacity, overcoming the geographical limitations of ground cellular communication, enabling multi-dimensional communication tasks in space and on the ground, and allowing emergency communication support in natural disasters. Currently, satellite communication systems play an important role in multiple fields such as transportation, aviation, logistics, agriculture, meteorology, and environmental protection. During the development process of these systems, the large scale and complex network of satellites pose challenges to the real-time stability and efficiency of transmission.

In order to support the development of satellite communication technology, this Special Issue focuses on the latest systems, high-speed high-order modulation communication technologies, advanced coding and modulation strategies, and their innovative applications in inter-satellite high-speed links, satellite–ground feeding links, and satellite–ground user links. It primarily includes research on the latest signal waveform design and communication signal processing theory.

Coherent free-space optical communication offers significant advantages in terms of communication capacity, making it particularly suitable for high-speed inter-satellite transmission within satellite communication networks. Nonetheless, the presence of Doppler frequency offset (FO) and phase noise (PN) associated with lasers adversely affects the bit error rate (BER) performance of these communication systems. Conventional methods for FO and phase estimation are usually hindered by high computational demands and phase cycle slips, especially in environments characterized by elevated channel noise. To address these challenges, a noise-tolerant method is proposed to facilitate accurate carrier phase recovery (CPR) with reduced complexity. This method merges a second-order feedback loop and a feedforward stage to achieve accurate estimation. The simulation results indicate that the proposed method surpasses traditional methods in terms of noise tolerance and resource efficiency. Particularly, the BER of the proposed method can be decreased to 6.7×10−3 at a signal-to-noise ratio (SNR) of 4.5 dB, in contrast to a BER of 0.25 for the traditional method. Additionally, the resource consumption of the proposed method can be decreased by 64% under equivalent conditions. Furthermore, the experimental results reveal that the phase estimation error and BER for the proposed method are 2.1×10−4 and 7.5×10−4, respectively, when the received power is −41 dBm. These values are significantly lower than those achieved with traditional methods, which obtain errors of 1.85×10−3 and a BER of 0.48, respectively. Full article
