26695 最后，通过仿真验证了分集IA的性能。 Finally, the diversity of the IA performance is verified by simulation.
26696 短波信道的时变特性将严重影响短波通信的传输效率，同时在短波IP(Internet protocol)组网通信中影响更为显著。 Time-varying characteristics of shortwave channel will seriously affect the transmission efficiency of short-wave communication, at the same time in shortwave IP (Internet protocol) network communication effect is more significant.
26697 为此，在短波IP数据传输中给出基于选择重发ARQ(selective repeat automatic repeat-requst，SR-ARQ)的自适应调整速率的短波通信系统。 To this end, in short wave IP data transmission is given based on the choice of retransmission ARQ (selective repeat automatic repeat - requst, SR - ARQ) rate of adaptive adjustment of shortwave communication system.
26698 系统选择有效吞吐率作为速率自适应阈值判决标准，得出了一般有效吞吐率表达式，以及不同速率判决的最佳阈值。 System choose effective throughput as rate adaptive threshold judgment standard, obtained the general effective throughput expression, and the best threshold value of different rate of judgment.
26699 理论分析和仿真验证了与单一速率系统相比较，系统吞吐率有明显提高。 Theoretical analysis and simulation verified the system compared with the single rate, the system throughput is improved obviously.
