提出了一种单载波频域均衡（SC-FDE）调制方案，该方案比以往的扩频技术方案获得更高的比特率，在研究中取得了进步。本报告工作的重点是利用极低功率高频电离层通信从遥感器传输数据。特别是，作者的研究小组自2003年以来一直在研究来自南极洲的电离层通道参数和数据传输技术。扩频调制和多载波调制都经过了测试，以便在误码率和比特率之间取得良好的平衡。对单载波技术的原理进行了验证，取得了令人满意的结果。
A single carrier frequency domain equalisation (SC-FDE) modulation scheme which represents a step forward in the investigation since it obtains higher bit rates than previous proposals with spread spectrum techniques is presented. The focus of this reported work is the data transmission from remote sensors using very low-power HF ionospheric communications. In particular, the authors' research group has been studying the ionospheric channel parameters and data transmission techniques from Antarctica since 2003. Both, the spread spectrum and multicarrier modulations have been tested previously in order to obtain a good trade-off between bit error rate and bit rate. A proof of principle of the single carrier technique with promising results is presented.
