Cognitive Radio Based on Space-Time Spectrum Sharing Research

中文摘要英文摘要

提出了一种更为实用的空时域结合频谱共享技术,深入探讨了影响其性能的指标,通过仿真分析可以得出,空时域结合频谱共享技术在频谱利用效率、用户通信中断概率、网络容量等方面的性能要优于传统的空域频谱共享技术及时域频谱共享技术。

In this paper, a more practical joint spatial and temporal spectrum sharing technique was proposed, and its key performance-inlfuencing factors were deeply discussed. Both analytical and simulation results concluded that the performance of joint spatial and temporal spectrum sharing is better than the ones of the traditional spatial spectrum sharing and the temporal spectrum sharing in spectrum efifciency, communication outage, and network capacity.
