摘要

介绍了采用幅度比较单边带(ACSSB)调制技术的陆地移动地球站的性能，以及在静态环境下、农村、郊区和城市进行的l波段(1.6/1.5 GHz)现场实验结果。实验结果表明，语音通信所需的载波与噪声功率密度比(C/No)大于40 dBHz，导频信号跟踪所需的C/No为34 dBHz。并将ACSSB系统与传统窄带调频系统进行了比较。功率谱密度分析表明，ACSSB系统的效率是NBFM系统的4倍。

Experiments on ACSSB land mobile satellite communications

The performance of a land mobile earth station using the amplitude companded single sideband (ACSSB) modulation technique, and results of field experiments which were conducted at L-band (1.6/1.5 GHz) in a static environment and in rural, suburban, and urban areas, are described. Results of the experiments show that the required carrier to noise power density ratio (C/No) for voice communications is greater than 40 dBHz and the required C/No for pilot signal tracking is 34 dBHz. A comparison of the ACSSB system with the conventional narrowband frequency modulation (NBFM) system is also carried out. The analysis of the power spectral density indicates that the ACSSB system is four times as efficient as the NBFM system.<>
