摘要
Abstract
A novel, special and highly efficient modulation system was proposed, which combined harmoniously EBPSK (Extended BPSK) modulation, digital impulsion filter, adaptive demodulation method and parameter-matching technology. The signal system of GNSS ISLs with novel modulation and demodulation was simulated and analyzed. The results show that the integrated index (bit/s/Hz/SNR) of the new signal system outperforms other present systems. And many important parameters of the new signal system, such as rate, band-width and SNR, may change with space environment.关键词
