摘　　要：介绍了三个短波多址接入协议:美军141B标准的第三代自动链路建立协议(3G ALE)、北约STANAG 4538标准的快速建链机制(FLSU)、以及北约STANAG 5066标准的短波令牌环协议(HFTRP)的技术特点,及其在短波组网中的应用。运用OPNET仿真软件对FLSU、3G ALE及HFTRP进行仿真建模,对比分析了在信道误码下的性能。仿真结果表明,在信道误码影响下FLSU最稳健,3G ALE次之,HFTRP受信道误码影响最大。Three HF multi-access protocols are discussed, including 3G ALE, FLSU and H^FRP, and their technical characteristics and applications in shortwave networks. Simulations on HFTRP,3G ALE and FLSU are done with OPNET software, and the performances of the three protocols compared and analyzed in HF channel Bit Error Rate （BER） conditions. Simulation results indicate that FLSU is the most robust of the three, 3G ALE ranks the second,and HNTRP is most heavily affected by HF channel with high BER.
