| 摘 要： | 针对宽带卫星信道,在频率衰落比较严重的情况下,传统的时域均衡算法具有较高的复杂度,因此,采用频域均衡(FDE)技术是比较可行的方案.对下行链路采用单载波频域均衡(SC-FDE)技术和OFDM技术进行比较,较详细地给出下一代卫星通信系统的下行链路中采用SC-FDE的性能.

| Abstract: | In broadband satelllite communication,the traditional time domain equalization has high complexity under severe frequency selective fading environment,thus frequency domain equalization(FDE) is a good choice in such scenario.SC-FDE and OFDM for downlinks are discussed and compared.Moreover,the performance of SC-FDE employed in the downlinks for next generation satellite communication is analyzed. |
