第三代短波通信HDL协议性能研究

我国第三代短波通信技术的研究仍处于起步阶段，并且国内的大多短波通信系统都是基于第二代的短波通信标准。相比于第二代短波通信的数据链路协议，第三代短波通信的自动链路建立系统以其简洁而高效的设计解决了第二代短波系统所面临的各种问题，在建立数据链路的高效性、稳定性、可靠性等方面都有了很大的改进。根据美军标MIL-STD-188-141B中给出的第三代短波通信技术标准，对第三代短波数据链路协议的高速数据链路传输协议（HDL）进行了研究，通过理论分析与Matlab仿真相结合的方法，对数据包的误码率、丢包率、平均传输次数以及采用不同数据分组时的吞吐量等方面进行了性能分析。

Performance analysis of the 3G-HF high-rate data link protocol

The domestic research on the 3rd generation HF communication technology is still at the primary stage and most HF radio system are based on the 2nd generation. Compared with the 2nd generation HF data link protocols, the 3rd generation HF data link protocols present much higher-efficient and superior. In this paper, we studied the performance of the 3G-HF High-Rate Data Link Protocol (HDL) based on the standard which defined in U.S. MIL-STD-188-141B. Considering the different conditions, we discuss the bit error rate, packet error rate, average transmission times and throughput performance by simulations and theoretical analysis.
